ABSTRACT

In this work, we have synthesized four 1-butyl-3-methylimidazolium carboxylate ionic liquids (ILs): 1-butyl-3-methylimidazolium glycolate ([C4mim][HOCH2COO]), lactate ([C4mim][CH3CHOHCOO]), benzoate ([C4mim][C6H5COO]), and glycinate ([C4mim][H2NCH2COO]). The transport properties such as viscosities and conductivities have been experimentally determined for these ILs at (303.15 to 343.15) K. From these data, the influences of substituent group in carboxylate anion and system temperature on viscosities and conductivities of the ILs have been examined. In addition, Walden plots have been plotted to investigate ionicity of the ILs, and the viscosity and conductivity data have been correlated by Vogel Fulcher Tammann (VFT) and Arrhenius equations.
