Thermophysical Properties of Ionic Liquid with Thiocyanate and Dicynamide Anions

摘要

In this work, density and viscosity of ionic liquids with dieynamide and thiocyanate anion were obtained. The thermal expansion coefficient values were obtained from the experimental density values. The density and viscosity of the ionic liquids depends on the nature of the cations. The density of the ionic liquids increases in the order of [BM1M]~+ <[AMIM]~+ < [BzMIM]~-< [HEMIM]~+ for dieynamide anion. Both for thiocyanate and dieynamide anions the viscosity values increase in the order of [BMIM]~+ < [AM1M]~+< [BMIM]~+< [HEMIM]~+. Moreover, viscosity values of ionic liquids with dieynamide anions are less than their corresponding thiocyanate anion.
