Abstract

Functional ionic liquids e.g., [BMIM]ZnCl3, [BMIM]Zn1.5Cl4 and [BMIM]Zn2Cl5 were prepared by zinc chloride dissolved in [BMIM]Cl ionic liquids. Dynamic viscosity and conductivity data of ionic liquid were measured at temperature ranging from 323.15-353.15 K with an interval of 5 K. Dynamic viscosity increased with the rise of ZnCl2 concentration and decreased with rise of temperature. The conductivity expressed an opposite results. The viscosity and conductivity at different temperature were well described by the Arrhenius equation and Vogel-Fulcher-Tammann (VFT) equation. All the correlation coefficients were above 0.98. The molar conductivity was calculated according to the conductivity and density data of ionic liquids. The relationship between the dynamic viscosity and the molar conductivity was discussed by Walden rule.
