Triethylamine → Bis(N,N-diethyl-N-methylethanaminium) carbonate

Participants

Reaction Steps

Into an autoclave equipped with a stirrer, triethylamine (1 mol), dimethyl carbonate (1.5 mol) and methanol (2 mol) as a solvent, were charged and reacted at a reaction temperature of 110° C. for 12 hours to obtain a methanol solution of methyltriethylammonium carbonate. Acetic acid (1 mol) was charged thereto, and as a solvent, ethylene glycol was added to a predetermined concentration. Then, by means of an evaporator, carbon dioxide formed as a byproduct and methanol were removed to obtain a solution comprising 50% methyltriethylammonium acetate and 50% of ethylene glycol.
