Conductivity of AlCl3-BMIC Ionic Liquid Mixtures Containing TiCl4 at Different Temperatures and Molar Ratios

The conductivity of the mixture of 1-butyl-3-methylimidazolium chloride (BMIC) ionic liquid with aluminum chloride (AlCl3) and titanium chloride (TiCl4) are systematically investigated over a range of temperature (70–110 °C) using the electrochemical impedance spectroscopy (EIS) method. The molar ratios of the components are changed to study the effect of molar ratio on the conductivity. The conductivity data are plotted against temperature to check whether it obeys the Arrhenius law. The activation energy and the density are calculated. The conductivity of the solution increases with increasing temperature for every composition. For varying molar ratio, conductivity increases with increasing TiCl4 content up to a certain composition then starts to decrease for each temperature. At room temperature, density of the solution increases with increasing TiCl4 content in the solution.
