AB  - Terpenes usually found in plants have a wide range of applications, especially as additives in various types of fuels, and most recently in the aviation industry, where they can be blended with jet fuels or kerosene. In this work, the densities of pure terpenes (1R)-(+)-α-pinene, (1S)-(−)-β-pinene, and linalool were measured over the temperature range T = (293.15 to 413.15) K and at high pressures p = (0.1 to 60) MPa. The experimental density data were fitted by the modified Tammann-Tait equation where the absolute average percentage deviation between measured and calculated densities was less than 0.02%, the percentage maximum deviation was less than 0.2%, and the average percentage deviation was less than 0.02% for all three measured terpenes. The obtained parameters were used to determine isothermal compressibility (κT), isobaric thermal expansivity (αp), internal pressure (pint), and the difference between specific heat capacity at constant pressure (cp) and constant volume (cv). Furthermore, the PC-SAFT model was applied for liquid density prediction at high pressures. Derived thermodynamic properties such as isothermal compressibility and isobaric thermal expansivity increase as temperature increases and decrease with pressure for all of the studied compounds.

AB  - This paper investigates the feasibility of using diethyl adipate (DEA), a green organic solvent, as a separation agent for extracting various alcohols from aqueous solutions. In order to achieve this, liquid-liquid equilibria (LLE) experiments were carried out for four ternary systems: {water + methanol + DEA}, {water + ethanol + DEA}, {water + 1-propanol + DEA}, and {water + 2-propanol + DEA} at 298.15 K and atmospheric pressure. LLE experiments involve determination of certain thermodynamic data such as binodal curves and cloud-point data. Binodal curve data were determined by the cloud-point method using the titration technique, while the tie-line data were determined by optimizing the parameters based on the experimental measurements of the refractive index. Additionally, the distribution coefficients and the separation factors were calculated within the immiscibility region. Hand and Othmer-Tobias correlations were used to examine the reliability of the tie-line data. Also, the experimental ternary LLE data were correlated using the UNIversal QUAsiChemical (UNIQUAC) activity coefficient models. The results confirm that that DEA is a suitable choice for extracting methanol, ethanol, 1-propanol, and 2-propanol from water. The potential of DEA as a separation agent followed the sequence methanol < ethanol < 2-propanol < 1-propanol. UNIQUAC model proved to be effective in correlating the LLE data.

AB  - Of major interest, especially in city environments, and increasingly inside vehicles or industrial plants, is the drive to reduce human exposure to nitrogen oxides (NOx). This trend has drawn increasing attention to filtration, which has developed remarkably owing to the capabilities of recently developed mathematical models and novel filter concepts. This paper reports on the study of the kinetic modelling of adsorption of nitrogen dioxide (NO2), collected from the tailpipe of a diesel engine, reacting to calcium nitrate salt (Ca(NO3)2) on a surface flow filter consisting of a coating of fine ground limestone or marble (CaCO3) in combination with micro-nanofibrillated cellulose (MNFC) acting as binder and humectant applied onto a multiply recycled newsprint substrate. The coating and substrate are both porous, but on different pore size scales, with the coating having significantly lower permeability. To maximise gas-coating contact, therefore, the coating deposition is pixelated, achieved by pin coating. An axially dispersed gaseous plug flow model (dispersion model) was used to simulate the transport within the coating pore network structure, following earlier flow modelling studies, and a kinetic reaction model was used to examine NO2 to NO3− conversion in correlation with experimental results. Modelling results indicate a 60.38% conversion of exposed NO2 gas to Ca(NO3)2 under the specific conditions applied, with an absolute relative error between the predicted and experimentally estimated value being 0.81%. The model additionally enabled a prediction of effects of changing parameters over a limited perturbation range, thus assisting in predicting filter element consumption, with attention given to the active component CaCO3 surface as a function of particle size in relation to the gas contact exchange, promoting the reaction over time. It is intended that the Ca(NO3)2 formed from the reaction can go on to be used as a value-added fertiliser, thus contributing to circular economy. Graphical abstract: (Figure presented.)

AB  - The uncontrolled and excessive use of fossil fuels is one of the main culprits for global warming due to the emission of greenhouse gases. Therefore, intensive work has been done to reduce the use of such fuels by replacing/adding biodiesel in transport sector since the use of biodiesel decreases the net emission of greenhouse gases by about 76 % than when using petroleum diesel (Ivaniš et al., 2016). On the other hand, the modern consumer lifestyle has led to the accumulation of large amounts of waste that additionally pollutes the soil and water, which indicates the necessity of a global transition from a linear to a circular economy where waste represents raw material. The disposal of used cooking oil is a huge problem because it is usually poured down drains, which leads to clogging of kitchen pipes and local sewage. Consequently, waste cooking oil drastically reduces the efficiency of wastewater treatment plants and is extremely harmful to the aquatic ecosystem. The reuse of used cooking oil in food is not recommended so other forms of recycling such as biodiesel production are preferred. Biodiesel is obtained by the transesterification reaction of vegetable oils with short-chain alcohol in the presence of a catalyst, and glycerine is produced as a side product. By applying heterogeneously catalysed transesterification reaction, such as the use of CaO as catalyst, the generation of waste during the purification of products is avoided. Eggshells are solid organic waste that is generally discarded without prior treatment, making it a hazardous waste. It is considered that the eggshell mainly (about 96 %) consists of CaCO₃, which offers the possibility of its revalorisation through CaO production (Waheed et al., 2020). As part of our research, waste hen’s eggshell was collected and annealed at 830 ̊C producing CaO, which was used as a catalyst in the biodiesel synthesis from used cooking oil. The thermodynamic and transport properties of the obtained biodiesel and crude glycerine were determined at wide ranges of temperature and pressure, which is relevant for their further use [1]. The measured properties of the obtained biodiesel meet the limits prescribed by the standard for biodiesel EN14214 which confirms that it can be used in diesel engines and heating applications. The obtained raw glycerine can be mixed with biomass residues and used in the production of pellets. In this way, the problem of accumulation of waste in the form of eggshells, used cooking oil and crude glycerine is solved and their revalorisation is carried out, which is fully in accordance with the postulates of the circular economy. Furthermore, biodiesel, as an environmentally friendly alternative to petroleum diesel, was obtained.

AB  - The negative impact of the use of fossil fuels on the environment has led to an increase in research in the field of renewable energy sources and intensified the production of biodiesel. The latter has caused the accumulation of a large amount of waste glycerol, since about 1 kg of crude glycerol is obtained for 10 kg of biodiesel. Crude glycerol is traditionally considered a low-value waste because of impurities and variable composition and its disposal was limited due to the harmful effects on the environment. To reuse this by-product of the transesterification reaction, in most cases it needs to be refined. However, crude glycerol purification requires additional costs while at the same time the glycerol market is already saturated and, consequently, the price of crude glycerol continues to decline. To avoid the accumulation of waste glycerol and pollution of the environment, it is necessary to find some applications for the raw glycerol obtained from the industrial production of biodiesel (Groesbeck et al., 2008).
Crude glycerol can be integrated with waste biomass, such as agricultural waste and wood residues, to improve its properties as a fuel. During the production of pellets, raw glycerol serves as a binder, which increases the yield and durability of pellets during storage and transportation. Additionally, it serves as a lubricant reducing the energy required for palletisation. It has been shown that when burning pellets with additional raw glycerol, a significantly lower amount of NOx is released than in the case of classic wood pellets (Zhang et al., 2022).
In this study, we investigated the possibility of adding waste crude glycerol to waste agro-industrial biomass in the production of enriched pellets. By applying the basic principles of the circular economy, the glycerol used for the purposes of this research was obtained from the transesterification reaction between used edible oil and short-chain alcohol, with the presence of a catalyst obtained from the waste shell of chicken egg. The characterization of the mixtures of different agricultural biomass and agro-industrial waste with different mass fraction of crude glycerol was performed. Standard analyses for determining the quality of pellets (such as calorific value, ash content, etc.) were performed to examine the possibility of using the enriched pellets obtained in this way in existing boilers designed for the use of commercial pellets.

AB  - The aim of this study was to examine the possibility of using a green organic solvent, dimethyl adipate (DMA), as a separation agent in the extraction of different alcohols from aqueous solutions. For that purpose, the liquid–liquid equilibria (LLE) of four ternary systems were analytically determined at 298.15 K and atmospheric pressure using stirred and thermo-regulated cells: {water + methanol + dimethyl adipate (DMA)}, {water + ethanol + DMA}, {water + 1-propanol + DMA}, {water + 2-propanol + DMA}. Phase diagrams for these four ternary systems were obtained by determining a binodal curve and tie-lines data using a visual cloud-point method, but also gas chromatography. Distribution coefficients and separation factors were calculated for the immiscibility region. Hand and Othmer-Tobias correlations were used to examine the reliability of the tie-line data. In addition, the experimental ternary LLE data were correlated with the UNIversal QUAsiChemical (UNIQUAC) activity coefficient models. The obtained results showed that DMA is a suitable candidate for the extraction of methanol, ethanol, 1-propanol, and 2-propanol from water. With some alcohols, this potential is more noticeable than with others. The potential of DMA as a separation agent is increasing in the following sequence: methanol < ethanol < 2-propanol < 1-propanol, and that also could be noticed from the selectivity values that also increase in this sequence. The UNIQUAC model proved as successful in correlating the LLE data.

AB  - This paper presents liquid-liquid equilibrium data for the ternary mixture of water + acetone + dimethyl phthalate at T = 298 K and atmospheric pressure. Due to the increase in energy consumption on a global level, it is necessary to examine new possibilities of replacing the classic energy-intensive separation processes that would be based on liquid-liquid extraction. Liquid-liquid
extraction is a cost-effective, efficient and, above all, environmentally friendly separation method in
industrial processes. This procedure would also involve the replacement of standard industrial solvents with environmentally harmful characteristics with new, green solvents. Dimethyl phthalate is a good candidate as a green solvent because it is relatively non-toxic, renewable and biodegradable.
Thermodynamic liquid-liquid equilibrium data such as the binodal curve and tie lines for the
corresponding system are necessary for the design of the separation process as well as for a better perception of the behaviour of multicomponent systems and the improvement of thermodynamic modelling and prediction of phase equilibrium.

AB  - The subject of presented research is the study of liquid binary mixtures consisting of ester and alcohol combination; triacetin or ethyl levulinate, as one component, and ethanol or isobutanol, as second component. Thermodynamic and transport data were measured in the broad temperature range, T=(288.15/298.15–323.15/333.15) K, and at atmospheric pressure, p = 0.1 MPa. All corresponding excess and deviation properties were calculated including the excess molar volume, viscosity deviation, refractive index deviation, isentropic compressibility deviation and excess molar Gibbs energy of activation of viscous flow, and correlated with the basic Redlich-Kister equation. The analysis of possible chemical interactions and structural effects taking place in the mixtures was led in the terms of ester structure, complexity of ester molecule and chain length and branching of the alcohol molecule. The thermodynamic analyses showed change of the sign of the excess molar volume depending on the alcohol present in the mixture. FT-IR spectra were recorded for all four systems for the compositions where maximum excess molar volumes are obtained to support the conclusions derived from the mixtures’ nonideal behaviour. In addition, modelling of viscosity is performed with the two- and three-parameter correlative models, as well as excess molar volume correlation with the Peng-Robinson equation of state and three-parameter van der Waals mixing rule.

AB  - This chapter aims to evaluate energy flows in the life cycle of biogas utilization (i.e., production of thermal energy, cogeneration, traffic, and production of hydrogen), starting from feedstock and anaerobic digestion, up to the digestate as fertilizer for agricultural production. The analysis is based on the out-turn of a bio­gas plant on the dairy farm Mirotin Vrbas, Republic of Serbia. Life Cycle Energy Assessment (LCEA), presented in this chapter, has demonstrated that three scenar­ios – biogas for heat production, biogas in cogeneration, and biomethane in trans­portation have positive energy balances, which indicate that in terms of replacement of fossil fuel consumption, these energy systems are promising alternatives. In the fourth scenario, where biogas is used for hydrogen production, the energy balance is negative, therefore socio-economical factors should be considered for overall consideration to ensure sustainability.

Life Cycle Energy Assessment (LCEA), presented in this chapter, has demonstrated that three scenar­ios – biogas for heat production, biogas in cogeneration, and biomethane in trans­portation have positive energy balances, which indicate that in terms of replacement of fossil fuel consumption, these energy systems are promising alternatives. In the fourth scenario, where biogas is used for hydrogen production, the energy balance is negative, therefore socio-economical factors should be considered for overall consideration to ensure sustainability.",

AB  - Due to the global trend of decreasing fossil energy sources consumption, there is a tendency, among other things, to explore possibilities of using biomass to obtain biofuels and value-added chemicals. In order to design processes as optimally as possible, it is necessary to know the thermodynamic properties of biomass components. One of the components that have been gaining in importance lately are furfural and furfuryl alcohol. The thermodynamic and transport properties such as density, speed of sound, refractive index and viscosity, of the binary system furfural + furfuryl alcohol were studied at various temperatures and pressures. Density of pure components was obtained in the temperature range (293.15–413.15) K for furfural and (293.15–373.15) K for furfuryl alcohol at pressure up to 60.0 MPa. The obtained density values were correlated using the modified Tammann–Tait equation. The thermodynamic properties of these components are of great importance in their further potential application.

AB  - The negative consequences of the use of fossil fuels, as well as the unsustainability of meeting ever-increasing energy requirements with limited reserves of fossil fuels, have led to the intensification of research in the field of renewable energy sources. Thermo-chemical conversion of biomass results in bio-oil with low energy density due to high oxygen content which can be upgraded by hydrodeoxygenation process (HDO). HDO consists of a number of reactions that can overlap so the process management requires knowledge on the thermodynamic properties of all compounds present in the biomass valorization process. 
Eugenol is promising biomass-derived platform chemical that, depending on used catalyst and reaction conditions, can be converted into a variety of important products including 4-propylguaiacol. Densities of eugenol and 4-propylguaiacol were measured at temperatures (293.15 – 413.15) K and pressures up to 60 MPa. The obtained results were correlated using the modified Tammann-Tait equation, which enabled the calculation of the valuable derived thermodynamic properties, such as the isothermal compressibility, the isobaric thermal expansivity, the internal pressure and the difference between isobaric and isochoric heat capacity. Densities of the binary mixtures eugenol + 4-propylguaiacol were measured at atmospheric pressure and temperatures (288.15 – 343.15) K to examine the influence of interactions between the studied 
components on the thermodynamic properties of their mixtures.

Kako bi se ispitale mogućnosti upotrebe zelenih rastvarača, mogućnosti adekvatne zamene i projektovanje procesa, neophodno je poznavanje termodinamičkih podataka kao što su podaci za ravnotežu tečnost-tečnost (LLE), odgovarajuću binodalnu krivu i ravnotežne linije. Podaci o rastvorljivosti komponenata su od velikog značaja za procese separacije (naročito ekstrakciju) koji se primenjuju u hemijskoj industriji. Ravnotežne linije predstavljaju veoma bitan termodinamički podatak koji se, u zavisnosti od same prirode komponenti koje ulaze u sastav smeše, u velikom procentu dobijaju hromatografskom analizom.

AB  - Due to the global trend of increasing environmental pollution, green solvents are being implemented in various branches of the chemical industry to, which would replace standard industrial solvents with harmful characteristics. In order to examine the possibilities of using green solvents, the possibility of appropriate replacement and process design, it is necessary to determine thermodynamic data such as liquid-liquid equilibria, i.e. tie lines in liquid- liquid extraction (LLE), and the corresponding binodal curve. Solubility of components are of great importance for the separation processes (especially for extraction) applied in the chemical industry. Tie lines are a very important thermodynamic data, which are mostly determined by chromatographic analysis depending on the nature of the components in the mixture. Tie lines are mostly determined by chromatographic analysis. Chromatographic analysis is one of the methods that not every laboratory can afford, due to the high cost of the apparatus and high operational costs. In this paper some of the alternative methods for determining tie lines in liquid-liquid equilibria are presented. On the example of the ternary system water+dimethyl adipate+2-propanol, the determination of tie lines via the refractive index and the density of the mixture are shown. These analytical methods are often used in various branches of industry. Based on the obtained results, a mutual comparison of the results obtained through these three methods is performed.

AB  - Water hyacinth biomass was used for the synthesis of activated carbons in the process of chemical activation with H3PO4, followed by controlled carbonization. The study investigates the effect of various impregnation weight ratios of H3PO4 and dry hyacinth (0.5–3.0), as well as different carbonization temperatures (T = 400–800 °C), on the surface characteristics of the produced activated carbons (AC). The activated carbon obtained with an impregnation ratio of 1.5 and a carbonization temperature of 600 °C (1.5 AC/600) showed the highest values of specific surface area of 1421 m2 g−1, representing a selected adsorbent for metformin removal. The chosen sample was characterized by elemental analysis, adsorption–desorption isotherms of nitrogen at −196 °C, via FTIR spectroscopy and the SEM method. The modeling of the experimental adsorption data showed that metformin adsorption: (i) can be best described by the Langmuir isotherm model, with the value of qmax = 122.47 mg g−1; (ii) led the pseudo-second order kinetic model; and (iii) is a spontaneous (ΔG° = −3.44 kJ mol−1) and endothermic (ΔH° = 8.77 kJ mol−1) process. A desorption study has shown that 92% of metformin was successfully desorbed in the presence of a 0.1 MHCl/ethanol mixture (volume ratio 2:1). The recovery of the adsorbent of 84%, after five successive cycles, indicated that the 1.5 AC/600 has potential to be applied in the real systems for water treatment.

AB  - Ethylene glycol is recognized as a heat transfer fluid. To improve its performance, caffeine is added to pure ethylene glycol. The experimental measurements of densities at pressures of up to 60 MPa and in the range of temperatures 293.15-413.15 K were performed. Obtained experimental results were fitted by the modified Tammann-Tait equation, and parameters were used to determine some valuable thermodynamic and mechanical properties, the isothermal compressibility, the isobaric thermal expansibility, the internal pressure, and the difference of specific heat capacity at constant pressure and constant volume. The same approach was applied to the equimolar mixture of ethylene glycol and water. The results confirm negligible changes in the investigated thermodynamic properties with the addition of caffeine into pure ethylene glycol and significantly smaller dependence on temperature compared to the mixture of ethylene glycol and water.

AB  - Three binary mixtures consisting of isoamyl acetate and 1-butanol or isobutanol or isopentanol were experimentally investigated in terms of their density, viscosity refractive index, and ultrasonic speed of sound, in the temperature range from 288.15 to 323.15 K and at atmospheric pressure. The choice of mixtures was based on their potential for practical application. From experimental data, excess molar volume, viscosity deviation, excess molar Gibbs free energy of activation of viscous flow, deviation in refractive index, and deviation in isentropic compressibility are calculated, correlated with the Redlich-Kister equation and used for better understanding of molecular interactions between the mixture components. Also, partial molar volumes, excess partial molar volumes, and partial molar volumes at infinite dilutions were calculated to elucidate the nonideal behavior of the investigated mixtures. Since the mixtures were investigated both from the theoretical point of view and with the aspect for practical application, the modeling of two key properties, viscosity and excess molar volume, was performed with different models and approaches, and the results are compared with experimental values.

AB  - Renewable hydrogen produced from the waste streams can be a good option for clean energy production and reduction of greenhouse gases emissions into the environment. In this study, the potential for hydrogen production from the food industry wastewaters in Serbia and the further use of the calculated potentials were investigated. This was performed through two technological routes including the biogas steam reforming process and the electrolysis after biogas cogeneration process. Furthermore, the environmental impacts of these processes were considered. The total hydrogen potential via the biogas steam reforming process was 4094.70 tons, while the total hydrogen potential via the electrolysis after biogas cogeneration process was 1751.08 tons. These potentials can be used for direct energy production in the food industry, electricity production for the national electric grid, transport, injection in the natural gas grid and/or as a resource in the chemical industry. Regarding the Greenhouse Gas emissions reduction, hydrogen production by both routes represents a promising pathway. The results of this work can serve the decision makers to plan hydrogen application in the energy sector of the Republic of Serbia defining supporting measures for its application. Also, the presented analysis is enforceable in the Western Balkan countries for the application of hydrogen as an energy source in their systems for energy production, transport and economy.

AB  - U cilju smanjenja zagađenja na globalnom nivou poslednjih godina aktuelna je tema zamene fosilnih goriva nekim novim biogorivima. Terpeni, koji su sastavni delovi biljaka, mogu se koristiti u ove svrhe kao dodatak standardnim gorivima. Neke od termodinamičkih svojstva pod uslovima visokog pritiska i određnih temperatura su od velike važnosti za efikasnost motora. U ovom radu su dobijene gustine linalola, alfa-pinena i beta-pinena u temperaturnom intervalu 293.15-413.15 K i na pritiscima do 60 MPa. Na osnovu ovih rezultata utvrđeno je da s porastom temperature pri konstantnom pritisku gustina navedenih terpena opada, dok sa povećanjem pritiska pri konstantnoj temperaturi gustina raste.
AB  - In order to reduce pollution at the global level in recent years, the main topic is replacing fossil fuels with some new biofuels. Terpenes, which are integral parts of plants, can be used for these purposes as an addition to standard petroelum fuels. Some of thermodynamic properties under high pressure conditions and moderate temperatures are of significant importance for engine efficiency. In this work, the densities of linalool, αpinene and β-pinene were obtained in the temperature range 293.15-413.15 K and at pressures up to 60 MPa. Based on these results, it was found that with increasing temperature at constant pressure the density of these terpenes decreases, while with increasing pressure at constant temperature the density increases.

AB  - The limited reserves and well-known disadvantages of using fossil energy sources have increased the need for appropriate renewable substitutes in the production of various chemicals and materials. Biomass has been shown to be worthy of attention since it can be converted to biofuels and value-added chemicals relatively easily. The design of biomass valorisation process requires knowledge on the thermodynamic behaviour of the biomass-derived compounds, such as furfural and furfuryl alcohol. The thermodynamic and transport properties of the binary system furfural + furfuryl alcohol were studied at various temperatures and pressures. Density, speed of sound and refractive index were measured in the temperature range T = (288.15–345.15) K and viscosity was measured at temperatures up to 373.15 K, all at atmospheric pressure. Further, the density of pure components was obtained in the temperature range (293.15–413.15) K for furfural and (293.15–373.15) K for furfuryl alcohol at pressures up to 60.0 MPa. The obtained density values were correlated using the modified Tammann–Tait equation with an average absolute deviation lower than 0.009% for furfural and furfuryl alcohol. The optimised parameters were used for the calculation of the isothermal compressibility, the isobaric thermal expansivity, the internal pressure and the isobaric and isochoric specific heat capacities. The reported data are a valuable source of information for the further application of the investigated compounds.

AB  - An experimental analysis of density, refractive index, speed of sound and the viscosity at atmospheric pressure and temperatures T = (288.15 to 323.15) K has been carried out for the three binary systems, i.e. (p-cymene + alpha-pinene), (p-cymene + limonene) and (p-cymene + citral). Excess molar volumes, viscosity deviations, deviations in isentropic compressibility and excess Gibbs free energy of activation of viscous flow were calculated from experimental data. The results were fitted employing Redlich-Kister polynomial equation. Also, partial molar volumes, excess partial molar volumes and partial molar volumes at infinite dilutions were calculated to elucidate the non-ideal behavior of investigated mixtures. Furthermore, Prigogine-Flory-Patterson (PFP) model was successfully applied for the correlation of excess molar volumes of examined binary mixtures. The results of excess molar volume correlations show very good agreement with experimental measurement.

AB  - In this work, experimental densities data of the binary system tetrahydrofuran + 2-butanol have been determined at eight temperatures, T=(288.15-323.15) K and atmospheric pressure and used for excess molar volume calculations. Also, partial molar volumes, excess partial molar volumes and partial molar volumes at infinite dilutions were calculated for further non-ideal behaviour of binary mixture. Excess molar volume, V-E, of experimental determined system tetrahydrofuran + 2-butanol, and four previously published binary systems, tetrahydrofuran + 1-butanol, dimethyl adipate + 1-butanol, dimethyl adipate + 2-butanol and dimethyl adipate + tetrahydrofuran were correlated with two models, Prigogine-Flory-Patterson (PFP) and Extended Real Association Solution (ERAS). In order to apply the proposed models additional data of ultrasonic speed of sounds for pure components, dimethyl adipate, tetrahydrofuran, 1-butanol and 2-butanol, were measured in the temperature range T=(288.15-323.15) K and at atmospheric pressure. Volumetric coefficients, thermal expansion coefficient alpha and isothermal compressibility kappa were calculated from density, ultrasonic speed of sound and isobaric heat capacity data. Isobaric molar heat capacities C-p,C-m at all temperatures for all pure components were obtained by correlation of literature data. Both models, PFP and ERAS were used for analysis of molecular interactions present in the investigated solutions.

AB  - Densities of four Deep Eutectic Solvents (DESs) based on menthol and organic acids (menthol:octanoic acid (1:1), menthol:decanoic acid (1:1), menthol:dodecanoic acid (2:1) and decanoic acid:octanoic acid (1:3)) were measured at high pressures (0.1 to 60) MPa and several temperatures (293.15 to 413.15) K. Tammann-Tait equation was used to model the experimental density data; the average absolute percentage deviations between calculated and experimental data were less or equal 0.012 %. The influence of the temperature and pressure on the derived volumetric properties: isothermal compressibility (k(T)), isobaric thermal expansivity (alpha(p)), internal pressure (p(int)) and difference between heat capacity at constant pressure (c(p)) and constant volume (c(v)) was analysed. Considering the experimental results, it is possible to observe that deep eutectic solvent formed by linear organic acids presents higher density values than those formed by menthol, being the densest the solvent formed by dodecanoic and octanoic acid. Attending to the derived volumetric properties in general, isothermal compressibility and isobaric thermal expansivity increase as temperature increases and decrease with pressure for all studied systems, being the octanoic acid based DESs slightly more compressible than the other studied DESs.
