“…The G* ,E values calculated by eq are listed in Tables S6–S9 and shown in Figure . For all the studied systems, the G* ,E values were positive over the whole compositional range with a maximum value in the cosolvent-rich region (0 < x 1 < 0.5), suggesting that the specific interactions of H-bonding resulted in the formation of complexes between the component molecules . The G* ,E value relates to both density and viscosity.…”

When using the same cosolvent, the G* ,E value of ChCl/Gly + MeOH or H 2 O at the maximum point was slightly larger (more positive) than that of ChCl/EG + MeOH or H 2 O, which was consistent with the observation from Δη and V E .…”

To study the effects of type and content of cosolvent as well as temperature on the properties of two well-known deep eutectic solvents (DESs), i.e., ChCl/EG (choline chloride + ethylene glycol at a molar ratio of 1:2) and ChCl/Gly (choline chloride and glycerol at a molar ratio of 1:2), the density and viscosity of the mixtures of ChCl/EG or ChCl/Gly with methanol (MeOH) and water (H2O) over the whole compositional range at temperatures from 288.15 to 323.15 K as well as the molar enthalpy of mixing for the mixtures of ChCl/EG or ChCl/Gly + MeOH were experimentally measured. The excess molar volume, viscosity deviation, and excess molar Gibbs energy of activation were further calculated to study the effects of temperature, types of cosolvent and DES, and their contents on the nonideal behavior of these pseudobinary systems. The molar enthalpy of mixing measured in this work was further compared with those with H2O as the cosolvent reported in the literature. It shows that the mixing of these two DESs with MeOH is exothermic, which is opposite compared to those mixed with H2O. Additionally, the nonrandom two-liquid model and Gibbs–Helmholtz equation were combined to represent the experimental results of the enthalpy of mixing.

Estimation of Excess Properties of Binary Liquids Systems of Tetrahydrofurfuryl Alcohol with Short-Chain Carboxylic Acids at 298.15 K

et al. 2019

At the temperature 298.15 K, some physical properties such as: refractive indices (nD), viscosities (η) and densities (ρ) were studied in four liquid-liquid mixtures: carboxylic acids (HCOOH, CH3COOH, CH3CH2COOH and CH3CH2CH2COOH) with tetrahydrofurfuryl alcohol (THFA) with the identified configuration set. These empirical data were utilized to estimate the excess molar volumes (Vm E ), refractive index perversions (∆R), viscosity deviations (η E ) and excess molar Gibbs free energy (∆G *E ). Values of Vm E , η E , ∆G *E and ∆R were plotted versus mole fraction of tetrahydrofurfuryl alcohol. In all cases, the values of Vm E , η E , ∆G *E and ∆R that obtained in this study were found to be negative at 298.15 K. The excess parameters were applied in the Redlich-Kister equation by utilizing multi-parameter coefficients that concluded binary coefficients and in respect to the standard deviation. The difference of these characteristics with the formation of binary liquid systems indicates the absence of bipolar bond, variation in the shape and size of component molecules, hydrogen bonding and dipolar interaction among unlike molecules.
