実験手順

By adding 50 parts of triethyl phosphate (TEP: produced by Daihachi Chemical Industries Co., Ltd.) to the methanol solution of 50 parts of 1-ethyl-3-methylimidazolium methyl carbonate salt obtained in Production Example 7 and carrying out a salt exchange reaction, there was obtained a methanol solution of 1-ethyl-3-methylimidazolium diethyl phosphate monoanion. The above-described solution was heated under reduced pressure of 1.0 kPa or less at 50° C. to distill methanol until no distillate of methanol was observed. Thereafter, the temperature was raised from 50° C. to 100° C. and heating was continued for 30 minutes to distill and remove monomethyl carbonate (HOCO2CH3), methanol, and carbon dioxide (slight amounts of methanol and carbon dioxide are formed by thermal decomposition of monomethyl carbonate. Hereinafter, these are abbreviated as by-products). Thus, 1-ethyl-3-methylimidazolium diethyl phosphate monoanion, electrolyte (C-4), was obtained. The yield was 99 parts (yield based on the weight of 50 parts of 1-ethyl-3-methylimidazolium methyl carbonate salt; hereinafter the same shall apply). The molecular weight of the electrolyte (C-4) was 266.
