Procedure

Triethylamine (1 mol), diethyl carbonate (1.5 mol), and methanol (2 mol) as a solvent were charged into a stirring-type autoclave, and the whole was reacted at the reaction temperature of 110° C. for 12 hours to obtain a methanol solution of methyltriethylammonium carbonate. 2-Ethylhexanoic acid (1 mol) was charged thereto and ethylene glycol was added as a solvent so as to be a predetermined concentration. Thereafter, a solution of 50% of methyltriethylammonium 2-ethylhexanoate and 50% of ethylene glycol was obtained by removing carbon dioxide and methanol produced as by-products by an evaporator.
