AB  - Density rho, viscosity eta and refractive index n(D) have been experimentally measured for four binary mixtures of poly(propylene glycol) of average molecular weight 425 + toluene/o-xylene/m-xylene/p-xylene over the temperature range T = (293.15-333.15) K with temperature step 5 K and at atmospheric pressure. From the experimental data excess molar volumes V-E, deviations in refractive index Delta n(D), viscosity deviations Delta eta and excess Gibbs free energy of activation of viscous flow Delta G(*E) were calculated and fitted with Redlich-Kister polynomial in order to analyze non-ideal behavior of the studied mixtures. From Delta G(*) values excess entropy AS(*E) and excess enthalpy of activation of viscous flow Delta H-*E were also calculated. It was shown that specific weak, but numerous, attractive interactions and entropic effect, due to difference in size of the pure component molecules, are responsible for volumetric and viscosity behaviour of the studied systems. The viscosities of the studied systems were predicted with the UNIFAC-VISCO and ASOG-VISCO models and correlated with the McAllister equation.

AB  - This article principally reviews our research related to liquid-liquid and solid-liquid phase behavior of imidazolium- and phosphonium-based ionic liquids, mainly having bistriflamide ([NTf2](-)) or triflate ([OTf](-)) anions, with several aliphatic and aromatic solutes (target molecules). The latter include: (i) diols and triols: 1,2-propanediol, 1,3-propanediol and glycerol; (ii) polymer poly(ethylene glycol) (PEG): average molecular mass 200, 400 and 2050 - PEG200 (liquid), PEG400 (liquid) and PEG2050 (solid), respectively; (iii) polar aromatic compounds: nicotine, aniline, phenolic acids (vanillic, ferulic and caffeic acid,), thymol and caffeine and (iv) non-polar aromatic compounds (benzene, toluene, p-xylene). In these studies, the effects of the cation and anion, cation alkyl chain and PEG chain lengths on the observed phase behaviors were scrutinized. Thus, one of the major observations is that the anion - bistriflamide/triflate - selection usually had strong, sometimes really remarkable effects on the solvent abilities of the studied ionic liquids. Namely, in the case of the hydrogen-bonding solutes, the ionic liquids with the triflate anion generally exhibited substantially higher solubility than those having the bistriflamide anion. Nevertheless, with the aromatic compounds the situation was the opposite - in most of the cases it was the bistriflamide anion that favoured solubility. Moreover, our other studies confirmed the ability of PEG to dissolve both polar and non-polar aromatic compounds. Therefore, two general possibilities of application of alternative, environmentally acceptable, solvents of tuneable solvent properties appeared. One is to use homogeneous mixtures of two ionic liquids having [NTf2](-) and [OTf](-) anions as mixed solvents. The other, however, envisages the application of homogeneous and heterogeneous (PEG + ionic liquid) solutions as tuneable solvents for aromatic solutes. Such mixed solvents have potential applications in separation of the aforesaid target molecules from their aqueous solutions or in extraction from original matrices. From the fundamental point of view the phase equilibrium studies reviewed herein and the diversity of the pure compounds - ionic liquids and target molecules - represent a good base for the discussion of interactions between the molecules that exist in the studied solutions.

AB  - The ability of binary deep eutectic solvent choline chloride+1,2-propanediol (DES1; 1 : 3 mole ratio) and ternary deep eutectic solvent choline chloride+1,2-propanediol+water (DES2; 1 : 3 : 3 mole ratio) for breaking the azeotropes hexane/heptane+ethanol by means of liquid-liquid extraction was evaluated. Liquid-liquid equilibrium experiments were performed at 298.15 K, at atmospheric pressure, and data were correlated by NRTL and UNIQUAC models. Thermodynamic properties (density, viscosity, refractive index and speed of sound) of DES1 and DES2 were determined in temperature range from 288.15 K to 333.15 K and at atmospheric pressure. Extraction ability of the investigated eutectics yielded promising results in comparison with conventional solvents. Besides a high selectivity towards ethanol, an advantage of DES2 is its lower viscosity and higher distribution ratio values, which is an important aspect for a potential industrial application. Another advantage of both investigated eutectics is their easy and high recoverability from the extract layer based on their negligible vapor pressure.

AB  - In this work novel solvent, poly(ethylene glycol) diacrylate (PEGDA) of average number molecular weight 700, is proposed for design of aqueous biphasic systems with salting-out agents: K3PO4/Na3C6H5O7/K2CO3/MnSO4/Li2SO4/ZnSO4. Ternary liquid-liquid equilibrium experiments were conducted at constant temperature 298.15 K and 0.1 MPa, where binodal curves and tie-lines were determined. The consistency of equilibrium data were checked and confirmed using Othmer-Tobias and Bancroft equations. Density rho, viscosity eta and refractive index n(D) have been experimentally measured for PEGDA 700 + water system over the temperature range T = (293.15 to 323.15) K with temperature step 5 K and at atmospheric pressure. Excess molar volumes V-E, viscosity deviations Delta eta, deviations in refractive index Delta n(D), excess Gibbs free energy of activation of viscous flow Delta G*(E), partial molar volumes (V) over bar (i), excess partial molar volumes (V) over bar (E)(i) and it's values at infinite dilutions (V) over bar (E,infinity)(i) were calculated from experimental data and used to analyze non-ideal behavior of polymer aqueous solution. Fourier-transform infrared analysis (FT-IR) of PEGDA + water mixture and corresponding pure components was performed at T = 298.15 K in order to gain insight into the molecular structure of the mixture. FT-IR analysis indicates the absence of hydrogen bonding between PEGDA 700 and water. This leads to the conclusion that non-ideal behavior of mixture is contributed to geometrical packing or van der Waals forces of different species.

AB  - The ability of non-toxic and biodegradable deep eutectic solvent (DES) choline chloride + DL-malic acid in mole ratio 1: 1, for the breaking of the azeotropes heptane + methanol and toluene + methanol by means of liquid-liquid extraction was evaluated. Ternary liquid-liquid equilibrium experiments were performed at 298.15 K and at atmospheric pressure. Densities, viscosities and refractive indices of DES + methanol and water + DES systems were experimentally determined over a wide temperature range and at atmospheric pressure. Additionally, the viscosities of DES + glycerol mixture were determined at temperatures up to 363.15 K to check how much the addition of glycerol decreases high viscosities of DES. The results indicate that the addition of small amounts of water or glycerol as a third component significantly decreases the viscosity of the investigated deep eutectic solvent. Based on the selectivity and distribution ratio values, the extraction ability of the investigated deep eutectic solvent, in comparison with the conventionally used solvents, yields promising results. Non-random two-liquid (NRTL) and universal quasichemical (UNIQUAC) models were satisfactorily applied for correlation of experimental phase equilibrium data for two ternary mixtures.

AB  - In this study, densities and viscosities of four binary systems {aniline/N,N-dimethylaniline + 1-butyl-3-methylimidazolium triflate ([bmim][OTf])} and {aniline/N,N-dimethylaniline + 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([bmim][NTf2])} were measured at atmospheric pressure and within the temperature range T = (288.15 to 333.15) K. Excess molar volumes V-E, viscosity deviations Delta eta and excess molar Gibbs energies of activation of viscous flow Delta G*(E) were calculated and the results were fitted to a Redlich-Kister polynomial equation. Also, enthalpic and entropic parts of the Delta G*(E) function were determined, at the same composition, for three studied systems that exhibit complete miscibility, since {aniline + [bmim][OTf]} is a partially miscible system. Considering the calculated thermodynamic properties, molecular interactions in the investigated binary systems were analysed and are discussed.

AB  - Industrial development during the last century has contibuted to pollution problem and depletion of fossil stocks due to unefficient processes which require more energy and chemicals. Sustainable processes in the future have to be oriented to less toxic and less volatile substances in order to reduce air, water and ground pollution. Solvents are basis for each industrial process and represent huge pollution source since toxic and volatile ones are in use currently. Therefore design of alternative ecological solvents and finding their application in exsisting processes is necessary. This thesis is dealing with potential industrial application of green solvents for treatment of toxic chemicals and azeotrope breaking. Thermodynamic properties of pure components and their mixtures were experimentally determined in wide temperature range T = (288.15 K – 333.15 K) and at atmospheric pressure. Densities , viscosities η and refractive indices nD were experimentally measured for polymers in the mixture with industrially important compounds like: aromatics, alcohols, esters. Same thermodynamic parameters were also experimentally determined also for non-toxic mixtures of polymers and ionic liquids, solvent mixtures of huge potential for industrial application. Choline chloride based binary eutectic mixtures and one ternary mixture with water as a third component were characterized in the same way in temperature range T = (298.15 K – 363.15 K). From experimental data excess molar volumes VE, viscosity deviations Δη and deviations in refractive index ΔnD were calculated and fitted with Redlich-Kister polinomial equation. Calculated properties were analyzed in terms of specific molecular interactions and geometrical effects between mixture’s components, taking into account temperature influence. Fourier transform infrared (FT-IR) spektroscopy of polymer + esters binary mixtures and corresponding pure components was performed at 298.15 K for the purpose of interpretation of molecular structure and possible intra- and inter-molecular interactions in solutions. For polyethylene glycol diacrylate + alcohol mixtures experimental data were correlated versus polyethylene glycol diacrylate mole fraction and temperature. Refractive indices of binary mixtures were predicted with various mixing rules (Lorentz-Lorenz, Dale-Gladstone, Eykman, Arago-Biot, Newton and Oster) and the results were compared with experimental data. Viscosity modeling was performed by two types of models: group contribution models UNIFAC-VISCO and ASOG-VISCO and correlative Teja-Rice and McAllister models. Experimental viscosity values were used for determination of new binary interaction parameters of various functional groups in order to be used in UNIFAC-VISCO and ASOG-VISCO models. Excess molar volume was modeled using Peng-Robinson-Stryjek-Vera cubic equation of state (PRSV CEOS) applying van der Waals one fluid and TCBT mixing rules...
AB  - Industrijski razvoj tokom prošlog veka doprineo je stvaranju problema zagađenja i trošenju fosilnih zaliha prouzrokovanom neefikasnim procesima koji zahtevaju veliki utrošak energije i hemikalija. Održivi procesi u budućnosti trebaju biti orijentisani ka upotrebi manje toksičnih i manje isparljivih supstanci u cilju smanjenja zagađenja vode, vazduha i tla. Rastvarači su osnov svakog industrijskog procesa i predstavljaju jedan od većih izvora zagađenja, s obzirom da su trenutno u upotrebi toksični i isparljivi rastvarači. Stoga je neophodan dizajn alternativnih ekoloških rastvarača i nalaženje njihove primene u postojećim procesima. U ovoj doktorskoj disertaciji ispitivana je potencijalna industrijska primena zelenih rastvarača za tretman toksičnih hemikalija i za separaciju azeotropa. Izvršena je termodinamička i fazna karakterizacija četiri tipa zelenih rastvarača: polimeri, jonske tečnosti, eutektičke smeše i dvofazni vodeni sistemi. Eksperimentalno su određivana termodinamička svojstva čistih komponenata i njihovih smeša u temperaturnom opsegu T = (288.15 K – 333.15 K) i na atmosferskom pritisku.

Pomenuti termodinamički parametri su eksperimentalno izmereni i za netoksične smeše polimera sa jonskim tečnostima, smeša rastvarača velikog potencijala za industrijsku primenu.

Iz eksperimentalnih podataka izračunate su dopunske molarne zapremine VE, devijacije viskoznosti Δη i devijacije indeksa refrakcije ΔnD koje su fitovane Redlich-Kister polinomom. Izračunate veličine su analizirane u pogledu specifičnih molekulskih interakcija i geometrijskog pakovanja između komponenata smeše, uzimajući u obzir i uticaj temperature.

Za smeše polietilen glikol diakrilata i alkohola eksperimentalni podaci su korelisani u funkciji od polietilen glikol diakrilat molskog udela i temperature.

Excess molar volumes V-E, viscosity deviations Delta eta, deviations in refractive index Delta n(D), excess Gibbs free energy of activation of viscous flow Delta G*(E), thermal expansion coefficients a, excess thermal expansion coefficients alpha(E), partial molar volumes (V) over bar (i), excess partial molar volumes (V) over bar (E)(i) and it's values at infinite dilutions (V) over bar (E,infinity)(i) were calculated from experimental data and used to analyze non-ideal behavior of mixtures. Fourier-transform infrared analysis of binary mixtures and corresponding pure components was performed at 298.15 K in order to gain insight into the molecular structure of mixtures and possible intermolecular interactions. Performed infra-red analysis confirms the presence of hydrogen bonding between unlike compounds, except for the system nicotine + 1-butanol. Here, the non-ideal behavior of mixtures is contributed to strong intermolecular interaction or in the case of nicotine + 1-butanol due to geometrical packing or dispersion forces of different species.

AB  - Experimental density rho, refractive index n(D) and viscosity eta data of three binary systems of poly(ethylene glycol) diacrylate (PEGDA) + ethanol, + 1-propanol and + 1-butanol were measured at eight temperatures from 288.15 to 323.15 K, with temperature step of 5 K, and at atmospheric pressure. The experimental data were correlated as a function of the PEGDA mole fraction and temperature. The densities and refractive indices of the investigated mixtures could be fitted well with exponential function vs. composition, including the temperature dependence of the parameters, while in the case of the viscosities, a polynomial function fits well the composition of the mixtures. In the case of the temperature correlation, all three properties (rho In eta and n(D)) exhibited linear trends. The viscosity modeling was performed using four models: the UNIFAC-VISCO, ASOG-VISCO, McAllister and the Teja-Rice models. For application of the UNIFAC-VISCO model, interaction parameters of following groups were determined: CH2=CH/CH3, CH2=CH/CH2, CH2=CH/OH, CH2=CH/CH2O and CH2=CH/COO. In addition, in the same way, the binary interaction parameters used in the ASOG-VISCO model of the following groups were determined: CH2=CH/CH2, CH2=CH/OH, CH2=CH/CH2O and CH2=CH/COO.

AB  - Densities, viscosities and refractive indices of four binary systems benzene + PEG 200, benzene + PEG 400, toluene + PEG 200 and toluene + PEG 400 were measured at ten temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, 318.15, 323.15, 328.15, 333.15 K) and at atmospheric pressure. From these data, excess molar volumes, viscosity deviations and deviations in refractive index were calculated and fitted to the Redlich-Kister equation. The obtained results have been analyzed in terms of specific molecular interactions and mixing behaviour between mixture components, taking into considerations effect of temperature on them. The refractive indices of binary mixtures were predicted by various mixing rules and compared with experimental data. The viscosity modelling was done by two types of models: group contribution UNIFAC-VISCO and ASOG-VISCO and correlative Teja-Rice and McAllister equations. The experimental values of viscosity were used to determine the interaction parameters of following groups CHar-CH2O, CHar-C-ar, C-ar-CH3, C-ar-CH2, C-ar-OH and C-ar-CH2O for their application in the UNIFAC-VISCO model. The same approach was used for calculation of following binary interaction parameters used in ASOG-VISCO model: CHar-CH2O, CHar-C-ar, C-ar-CH2, C-ar-OH and C-ar-CH2O.

AB  - In this paper, densities and viscosities of the solutions of PEG200 with two imidazolium ionic liquids, 1-ethyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}amide ([C(2)mim][NTf2]) and 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([C(2)mim][OTf]), at pressure 0.1 MPa and in the temperature range of 288.15-318.15 K, were measured. The experimental data were used to calculate excess molar volumes, deviations in viscosity and excess molar Gibbs free energies of activation of viscous flow for the studied solutions. Excess molar volumes indicate strong attractive interactions provoked by the studied ionic liquids which are even enhanced in the case of the [C(2)mim][OTf] as a solution component. The analysis of the viscosity data showed that these cannot be solely explained on the basis of the interactions between the present molecules/ions and that the factors also related to entropy - size and packing of molecules - must be considered as well. Thus, excess molar Gibbs free energy of activation of viscous flow appeared as very important for a complete description of the current viscosity behavior.

AB  - Liquid-liquid and solid-liquid phase behaviors of the binary solutions of imidazolium [C(2)mim](+) or trihexyltetradecyl phosphonium [P-6,P-6,P-6,P-14](+) ionic liquids having triflate [OTf](-), bistriflamide [NTf2](-) or ethyl-sulfate [EtSO4](-) anions with poly(ethylene glycol) (PEG) of average molecular mass (Mw) 200, 400 and 2050, were studied. The respective temperature-composition phase diagrams were constructed thus mapping the homogeneous and heterogeneous regions of the studied solutions. The impact of cation, anion and of PEG polymer chain length on the studied phase behavior was investigated and discussed in the terms of the important interactions in the solutions - hydrogen bonds and ion-dipole interactions. Imidazolium cation showed significant advantage over the phosphonium in promoting both liquid-liquid and solid-liquid solubility. On the other hand, the anion effect was found to be dependent on the outcome of the interplay between cation-anion and anion-PEG interactions. As expected, longer PEG chain led to worse solubility with the studied ionic liquids. This study is a first step to explore the possibilities to use the studied (PEG + ionic liquid) solutions as potential sustainable hybrid materials or combined (mixed) solvents of tunable thermophysical properties and/or solvent power.

AB  - In this work, liquid-liquid and solid-liquid equilibria (LLE and SLE, respectively), at atmospheric pressure, of the solutions of poly(ethylene glycol) (PEG) with several organic solvents were studied. The studied solvents include benzene, toluene, o-xylene, p-xylene, tetrahydrofuran (THF), pyridine, nicotine, aniline, 1-hexanol, 1-octanol and 1-decanol. Previous and present solubility tests showed that pyridine, nicotine, THF and aniline are completely soluble in liquid PEG200 and PEG400. This study confirmed and extended the previous discoveries that PEG can adjust its polarity and may be soluble with both polar and non-polar compounds as well as that the addition of a methyl group dramatically reduces the solubility of PEG with arenes. These remarkable features were thoroughly reviewed and discussed. Further on, they were used to explain the new results brought by this work - LLE of the solutions of (liquid) PEG200/or PEG400 with xylene isomers and SLE of the solutions of (solid) PEG2050 with all the aforementioned compounds. Molar excess volumes (V-E) of the solutions (PEG200/or PEG400 + benzene/or toluene) were measured at 298.15 K - these results were used to additionally discuss and explain the LLE behavior of these solutions. Finally, the results of this study showed the possibilities for sustainable applications (i) of liquid PEG200/or PEG400 for the separation of of o-xylene from p-xylene and (ii) of (solid) PEG2050 for benzene, toluene, pyridine and aniline treatment.

Further on, they were used to explain the new results brought by this work - LLE of the solutions of (liquid) PEG200/or PEG400 with xylene isomers and SLE of the solutions of (solid) PEG2050 with all the aforementioned compounds. Molar excess volumes (V-E) of the solutions (PEG200/or PEG400 + benzene/or toluene) were measured at 298.15 K - these results were used to additionally discuss and explain the LLE behavior of these solutions. Finally, the results of this study showed the possibilities for sustainable applications (i) of liquid PEG200/or PEG400 for the separation of of o-xylene from p-xylene and (ii) of (solid) PEG2050 for benzene, toluene, pyridine and aniline treatment.",
