Conductivity of 1-butyl-3-methyl-imidazolium chloride solutions in alcohols

This work presents the ionic conductivity of 1-butyl-3-methylimidazolium chloride [bmim][Cl]'s solutions in alcohols (ethanol, 1-butanol, 1-hexanol, 1-octanol, 1-decanol, 2-butanol, 2-methyl-2-propanol) and that of pure alcohols measured in wide range of temperature and concentration. The values of limiting conductance were determined by the Onsager limiting law. The molar conductivities of these systems were presented as a function of temperature and concentration. The mathematical description of ionic conductivities data by the Vogel-Tammen-Fulcher equation was made. It was shown that the conductivity of [bmim][Cl]'s solutions in the relatively low dielectric constant media is affected by the length of an alcohol carbon chain.
