Procedure

To a solution of 16 g of N-ethylimidazole in 20 ml of ethanol was added dropwise 25 g of trifluoromethanesulfonic acid at 0° C. After returning to room temperature, the solution was stirred overnight and dried in vacuo at 60° C. for 16 hours to give N-ethylimidazolium trifluoromethanesulfonate (hereinafter referred to as EtIm+TfS−) as a colorless transparent liquid. The melting point of the resulting salt (literature value: 7.8° C.,) was measured by DSC analysis. As a result, endothermic peaks were observed at 6.3° C. and 21.0° C.
