摘要：

This study presents the results from the measurements and further analysis of densities and viscosities of pure 1-ethyl-3-methylimidazolium ethyl sulfate, EMISE, and its binary mixtures with ethylene glycol, EG, over the entire composition range. Measured at atmospheric pressure from 293.15 to 343.15 K. A first-order polynomial equation was fitted to experimental density values of the EMISE + EG binary mixtures, whereas Vogel-Fulcher-Tammann (VFT) equation was used to fit viscosity data. Volumetric and excess properties have been determined. The excess molar volumes and viscosity deviations were correlated by the Redlich–Kister polynomial equation. Additionally, several selected semi-empirical viscosity models for EMISE + EG binary mixtures were tested, and coefficients were obtained. The thermal expansion coefficients of EMISE + EG binary mixtures were calculated. The intermolecular interactions between components were discussed. The results showed that in addition to the intermolecular interactions between components, packing effects due to the molecular size caused changes in properties.
