Ionic liquid (IL) usually possesses high viscosity. In this work, the selected organic solvents, namely, dimethyl sulfoxide, N,N-dimethylacetamide, and N,N-dimethylformamide, were used as the diluents to lower IL viscosity. The thermophysical properties of the densities and viscosities for the binary mixtures of IL (i.e., 1-octyl-3-methylimidazolium acetate) with solvents were studied at normal pressure in the temperature ranges of 303.15 K to 348.15 K. The effects of the organic solvents on lowering IL viscosity were quantitatively evaluated. The excess properties of the mixtures were calculated to analyze the interactions between IL and solvents. The hard-sphere model was employed to reproduce the viscosity behavior of the pure substances and binary mixtures.

In this work, densities, viscosities and vapor pressures of dimethyl sulfoxide (DMSO) + 1-allyl-3-methylimidazolium chloride (AmimCl) mixtures have been experimentally determined. Densities and viscosities were measured at temperatures T = [293.15, 373.15] K and molar fractions of dimethyl sulfoxide xDMSO = 0, 0.05, 0.1, 0.15, 0.25, 0.5, 0.75, 0.9 and 1 at atmospheric pressure with a Stabinger densimeter-viscosimeter. Viscosities and densities were found to decrease with increasing temperature and DMSO concentrations. Correlation of viscosity was made as a function of temperature and concentration with two modifications of the Seddon and Grunberg-Nissan equation, one with an average relative deviation of 6.8% and the second one of 16.3%. Vapor pressures of the mixtures were measured at T = [353.1, 433.1] K. and were correlated with Non-Random-Two-Liquid (NRTL) model, obtaining ARD% between 5 and 12%.

The ionic liquid (IL) of 1-hexyl-3-methylimidazolium acetate is widely used in chemical and bio-chemical processes. In this work, due to the high viscosity of IL, the promising chemicals (i.e., N, N-dimethylacetamide, N, N-dimethylformamide, and dimethyl sulfoxide) were selected as the additives to lower IL viscosity. The thermophysical properties of density and viscosity for IL with solvents were measured using a digital vibrating U-tube densimeter and an Ubbelohde capillary viscometer from 303.15 to 338.15 K at atmospheric pressure (0.0967 MPa), respectively. The influences of the solvents on the thermophysical properties of ionic liquid were quantitatively studied. Furthermore, based on the measurement values, the derived properties of excess molar volumes, thermal expansion coefficient, and the energy barrier were calculated, and the results showed that the mixture composition had great impact on excess volume change and viscosity. The hard-sphere model was employed to reproduce the viscosity. The infrared spectroscopy was performed to study the chemical structure to further understand the interactions between IL and the solvents.
