Abstract

This work is on the synthesis of EMI-BF4 (1-ethyl-3-methylimidazolium tetrafluoroborate) and purification of spectroscopic grade using aluminium oxide method, activated charcoal method, and liquid/liquid fractional extraction method in order to make supercapacitor finally. But the aluminum oxide method and the activated charcoal method were not suitable for obtaining high-purity ionic liquids. The liquid/liquid fractional distillation method turned out that as the concentration of solvent (H_2O) was increased, the higher purity of EMI-BF_4 was obtained and the electrical capacity of this compound was increased to higher value. When the solvent was changed to from methylene chloride to 1,2-dichloroethane, the higher purity of EMI-BF_4 was obtained.
