AB  - Densities, viscosities, and refractive indices of four binary systems, (PEG200 + 1,2-propanediol), (PEG200 + 1,3-propanediol), (PEG400 + 1,2-propanediol), (PEG400 + 1,3-propanediol) were measured at 10 temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, 318.15, 323.15, 328.15, and 333.15) K and at atmospheric pressure. 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.

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  - 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.
