Versuchsvorschrift
By adding triethyl phosphate (TEP, produced by Daihachi Chemical Industries Co., Ltd.) (0.1 mol) to a methanol solution of 1-ethyl-3-methylimidazolium methyl carbonate salt (0.1 mol), adding water (0.3 mol) and stirring the mixture at 100° C. for 20 hours, the triethyl phosphate was hydrolyzed and, at the same time, a salt exchange reaction was performed. As a result, a methanol solution of 1-ethyl-3-methylimidazolium diethyl phosphate monoanion was obtained. The resulting solution was heated at a pressure reduction degree of 1.0 kPa or less at 50° C., so that methanol was evaporated until methanol was no longer distilled off. By increasing the temperature from 50° C. to 100° C. and heating the mixture for 30 minutes to distill by-products off, an electrolyte (c10) {1-ethyl-3-methylimidazolium diethyl phosphate monoanion} was obtained. The yield was 98 wt %. The content of diethyl phosphate in the anions was 99% by mol.
