ABSTRACT

Data for the conductivity, e, of selected binary mixtures of the ionic liquids [emim][BF4], [bmim][BF4], [bmim][PF6], [bmim][DCA], and [hmim][BF4] with polar solvents (water, propylene carbonate, dimethylsulfoxide, methanol, dichloromethane) at 25 deg C are reported. Additionally, mixture densities, F, were determined to convert e into molar conductivity, E. The obtained results were fitted by appropriate interpolation formulas. Where possible, data were compared with information from the literature. Electrode polarization and sample purity, including [BF4 -] hydrolysis, were considered as possible sources of errors in e. The effect of viscosity on the accuracy of F and thus E was checked.
