中文摘要：

In order to understand the interactions of the mixtures of ionic liquids with different organic solvents,density,conductivity and refractive index have been investigated for binary mixtures of 1-allyl-3-methyl-imidazolium chloride( [AMIM]Cl) with acetonitrile,ethanol,and dimethyl sulfoxide( DMSO) at 298. 15 K. Density and refractive index were found to increase with increasing [AMIM]Cl concentration. Conductivity was found to increase initially by the addition of [AMIM]Cl. However,as the amount of [AMIM]Cl increases,a gradual decrease in conductivity of the mixtures has been observed. The resultant properties were caused by subsequent ion-ion and / or ion-solvent interactions depending on the extent of polarity,dielectric constants and miscibility of organic solvents being used.
