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.

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.

The obtained temperature-composition phase diagrams showed that the only functional co-solvent was PEG2050 for aniline in water, while PEG35000 even showed a clear anti-solvent effect in the N,N-dimethylaniline aqueous system. The experimental solid-liquid equilibria (SLE) data have been correlated by the non-random two-liquid (NRTL) model, and the correlation results are in accordance with the experimental results.

AB  - This work is a continuation of previous studies on phase demixing - salting-out effects in aqueous nicotine solutions. Thus, pH measurements were performed, allowing a brief analysis of the existing hydrogen bond interactions. Salting-out effects the related experimental cloud point shifts provoked by the addition of two inorganic salts, potassium nitrate and sodium sulfate, which have not hitherto been studied, were determined. Analysis of the current and previously reported salting-out/or salting-in phenomena in nicotine aqueous solutions was performed. In this respect, five studied salts were included: four inorganic salts (sodium chloride, potassium nitrate, sodium sulfate and trisodium phosphate (Na3PO4)), and ionic the liquid 1-ethyl-3-methylimidazolium ethyl sulfate ([C(2)mim][EtSO4], commercial name ECOENG212 (R)). Based on pH measurements, the effective Gibbs energies of hydration and the ionic strengths of the respective ternary solutions were calculated and plotted against the related cloud-point shifts caused by the addition of the salts. For the studied salts, the results and diagram obtained within this work may be used to predict the cloud-points shifts, based on the related quantities of the salts added and/or the molar Gibbs energies of hydration and/or ionic strengths requested in each case.

abstract = "This work is a continuation of previous studies on phase demixing - salting-out effects in aqueous nicotine solutions. Thus, pH measurements were performed, allowing a brief analysis of the existing hydrogen bond interactions. Salting-out effects the related experimental cloud point shifts provoked by the addition of two inorganic salts, potassium nitrate and sodium sulfate, which have not hitherto been studied, were determined. Analysis of the current and previously reported salting-out/or salting-in phenomena in nicotine aqueous solutions was performed. In this respect, five studied salts were included: four inorganic salts (sodium chloride, potassium nitrate, sodium sulfate and trisodium phosphate (Na3PO4)), and ionic the liquid 1-ethyl-3-methylimidazolium ethyl sulfate ([C(2)mim][EtSO4], commercial name ECOENG212 (R)). Based on pH measurements, the effective Gibbs energies of hydration and the ionic strengths of the respective ternary solutions were calculated and plotted against the related cloud-point shifts caused by the addition of the salts. For the studied salts, the results and diagram obtained within this work may be used to predict the cloud-points shifts, based on the related quantities of the salts added and/or the molar Gibbs energies of hydration and/or ionic strengths requested in each case.",

AB  - Viscosities of four binary mixtures: pyridine + PEG200, pyridine + PEG400, nicotine + PEG200 and nicotine + PEG400 have been measured in temperature range 288.15-333.15 K with temperature step of 5 K and at the atmospheric pressure. Viscosity deviations and excess molar Gibbs energies of activation of viscous flow for the selected binary systems were calculated from the experimental data and fitted to the Redlich-Kister polynomial equation. In addition, UNIFAC-VISCO and ASOG-VISCO models were used to predict the dynamic viscosities of the investigated binary mixtures. The experimental values of viscosity for the investigated four binary systems were used to determine the new interaction parameters for their application in UNIFAC-VISCO and ASOG-VISCO models. The viscosity data have also been correlated by two parameters Teja-Rice and three and four parameters McAllister models.

From these data, excess molar volumes, viscosity deviations and deviations in refractive indices were calculated and fitted to the Redlich-Kister equation. The obtained results have been analyzed in terms of the existing specific molecular interactions and the observed mixing behavior between mixture components, taking into considerations the related effect of temperature. The correlations of V-E binary data were performed by the Peng-Robinson-Stryjek-Vera cubic equation of state (PRSV CEOS) coupled with the van der Waals (vdW1) mixing rule and CEOS/G(E) mixing rule introduced by Twu, Coon, Bluck and Tilton (TCBT). 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: predictive UNIFAC-VISCO and correlative Teja-Rice and McAlister equations. In addition, the experimental values of viscosity were used to determine the new CH2O-CH3, CH2O-CH2, CH2O-CH, CH2O-OH, CH-CH3, CH-CH2 and CH-OH interaction parameters for their application in the UNIFAC-VISCO model.

Different temperature dependences of the NRTL parameters were tested on thirteen literature experimental liquid-liquid equilibrium data for binary systems.

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.

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.

AB  - Liquid-liquid equilibria were measured for solutions containing: (1) nicotine, and one of the solvents PEG 200 or ethyl-lactate, and the ionic liquid 1-ethyl-3-methylimidazolium ethyl sulphate (ECOENG 212 (R)); (2) a (nicotine + water) mixture of close to critical composition and one of the co-solvents PEG 200, or glycerol, or ethyl-lactate; and (3) a (nicotine + water) mixture and one of the salts ECOENG 212 (R), or sodium chloride, or sodium phosphate. The objective of these measurements was to assess the possibility of using environmentally friendly solvents for extraction/separation of nicotine from its (aqueous) solutions. PEG 200, glycerol and ethyl-lactate proved to be good co-solvents of nicotine in water. On the other hand, the inorganic salts Na3PO4 and NaCl showed remarkable salting-out effects in nicotine aqueous solutions, achieved using very small quantities of these salt. The effects of the ionic liquid (molten salt) ECOENG 212 (R), were, however, much more complex. Depending on its concentration in the solvent, it exhibited either a co-solvent (salting-in) effect or an anti-solvent one. This behaviour is very interesting both from the fundamental and the applications point of view.

AB  - Densities and molar excess volumes of the solutions of pyridine or nicotine in liquid polyethylene glycol, PEG200 and PEG400, have been determined at several temperatures. The experimental molar excess volumes are negative, thus indicating strong attractive interactions between the components, as could be expected considering their highly polar nature and good hydrogen bond abilities. For the pyridine systems, this negativity is slightly increased as the temperature rises, while the opposite tendency is observed for the nicotine mixtures. When pyridine and nicotine solutions are compared, the former particularly those with PEG400-exhibit substantially more negative molar excess volumes than the latter. The effect of the polymer chain length on the results for the nicotine solutions is almost negligible. However, this is not the case when pyridine is one of the components: a longer chain induced considerably higher compression on mixing. The Fourier-transform infrared analysis allowed interpretation of the negative experimental molar excess volumes in terms of specific inter- and intramolecular interactions.
