摘要

Abstract

Physical properties including refractive index

density

viscosity and conductivity for binary mixtures of 1-butyl-3-methyl imidazolium chloride ([BMIM]Cl) and different organic solvents at 298.15 K have been investigated. Excess molar volumes have been calculated and obtained data has been fitted by the Redlich-Kister equation. The density and refractive index were found to increase with increasing concentration of [BMIM]Cl

however

exceptions do exist as in the case of dimethyl sulfoxide (DMSO)/[BMIM]Cl. For DMSO/[BMIM]Cl

the density decreases with increasing concentration. The addition of different organic solvents was able to disrupt the interactions within mixtures

leading to freemobility of ions. The freemobility of ions has been found to enhance conductivity and decrease viscosity to varying extents in allmixtures studied. It has been observed that solubility parameters

dielectric constants and composition of the solvents used play a vital role in determining the resultant properties. The data obtainedwill play an important role in understanding the effect of the addition of organic solvents in ILs to enhance their applicability.
