“…Low viscosity is the main requirement for potential applications of ILs, which can directly affect conductivity, diffusivity, dispersion, mixing, filtration, and even equipment selection . Due to the high viscosity of ionic liquids, its conductivity is relatively low, and therefore, they often mix/dilute organic solvents such as acetonitrile, GBL, and PC. , Vraneš et al investigated the volumetric properties and transport properties of ionic liquid [bmim][NTf 2 ] and the PC mixture system as a function of temperature and composition, and the volumetric properties of n -methyl-2-pyrrolidone binary mixtures with GBL and PC were also been invenstigated . Papović, et al synthesized six binary systems of based ionic liquids [emim][NTf 2 ] with GBL and studied the influence of the composition on the electrical conductivity of (IL + GBL) binary mixtures …”

In this paper, thermodynamic properties such as density, conductivity, and viscosity of an ether-based-functionalized ionic liquid (IL) 1-(2methoxyethyl)-3-methylimidazole thiocyanate [MOEMIM][SCN] was measured at temperatures from (288.15 to 343.15) K and at atmospheric pressure (101 KPa). Then, the mixture systems blends of [MOEMIM][SCN] + 1,4-butyrolactone (GBL) or propylene carbonate (PC) were also prepared and measured over the whole composition range at the same temperature and pressure conditions. The Vogel−Fulcher−Tamman (VFT) equation was employed to describe the temperature dependence of transport properties (viscosity and conductivity). The Casteel− Amis four-parameter (C−A) equation was used to explain the mole fraction dependence of ILs on the electrical conductivity. From the experimental density and viscosity, the excess molar volume (V E ) and viscosity deviation (Δη) were obtained, and fitting results of the Redlich−Kister (R−K) polynomial equation showed that the changes of the excess properties were reasonable for the mixtures. Combined with the COSMO−RS model based on DFT calculation, the intermolecular interaction situations of the mixture systems were evaluated. Further, the σ-profile can provide the computational aspect of specific interactions between molecules or between solvent through H-bond donors and H-bond acceptors.

“…O volume molar excesso apresenta valores negativos quando, após a mistura, a solução final tem seu volume reduzido devido às diferenças de tamanho e volume dos reagentes, interações intermoleculares mais fortes entre as diferentes espécies químicas e/ou acomodação intersticial entre as moléculas. Por outro lado, quebra de ligações de hidrogênio de álcoois agregados, decréscimo de associação dipolo entre compostos polares, impedimento estérico e/ou interações mais fracas resultam em valores positivos (BAHADUR, 2008;VRANEŠ et al, 2015). Outros efeitos estruturais, químicos e físicos podem contribuir positiva ou negativamente para o volume molar excesso.…”

Substances derived from biomass have called attention, once these compounds belong to the group of renewable solvents, whose physicochemical properties present great potential for applications in several areas of science and industry, namely in biorefineries. Therefore, thermodynamic properties of systems containing such liquids is of practical interest, because experimental data can be used in modeling in order to improve processes or yet to develop and verify new models and solution theories, which have shown their complexity. The present project aims at studying excess thermodynamic properties, that quantify the real solution deviation in comparison to the ideal one, and spectroscopic analyses of binary liquid systems constituted of gamma-valerolactone (GVL) + alcohols (ethanol, 1-propanol, 1-butanol or 1- pentanol). For this purpose, original values of density, speed of sound and dynamic viscosity were determined for these solutions in the whole composition range and in temperatures T = (293.15 – 313.15) K under ambient pressure (92.3 kPa). From these experimental results, it was possible to calculate volumetric properties such as excess molar volume (Vm E ), acoustic property as deviation in isentropic compressibility (??S), viscometric as deviation in viscosity (??) and excess Gibbs energy of activation of viscous flow (?G *E). These properties resulted in negative values at all conditions, except for Vm E , which was totally negative only in ethanol-GVL system. To complete the thermodynamic discussion, both nuclear magnetic resonance (1H-NMR and 13C-NMR) and infrared (ATR-FTIR) spectroscopies have been performed, whose spectra proved the existence of weak hydrogen bondings between GVLalcohol
