Procedure

Into an autoclave equipped with a stirrer, didecylmethylamine (1 mol), dimethylcarbonate (1.5 mol) and methanol (2.0 mol) as a solvent were introduced, and a reaction was carried out at a reaction temperature of 110° C. for 12 hours to obtain a methanol solution of dimethyldidecyl ammonium methylcarbonate. To this solution, octylic acid (1 mol) was added, and by removing carbon dioxide and methanol, which were formed as byproducts, dimethyl didecylammonium/octylate (quaternary ammonium salt (B1)) was obtained.
