Study of effect of water on the physicochemical properties of 1-buthyl-3-methylimidazolium Chloride ionic liquids
The density,viscosity,conductivity and the electrochemical window of 1-buthyl-3-methyl-imidazolium Chloride ionic liquids(BmimCl) and its water mixture have been determined at 298.15 K and atmospheric pressure.It was found that the density and conductivity of BmimCl/water,increase with the increase the water concentration at the same temperature,whereas the viscosity and electrochemical windows of BmimCl/water decrease.The viscosity of pure ionic liquids decreases with the increase of the temperature,whereas the conductivity increases.The relationship between the conductivity and the temperature agrees well with the Arrhenius equation k =k∞exp-Ea/kBTand the active energy of conduction is determined accordingly.
