PURPOSE: To easily obtain an oxidized amine useful for a shampoo or a hair conditioner in high yield by reacting a tertiary amine with aq. H2O2, using a specific accelerator by a synergistic combination.
CONSTITUTION: A tertiary amine and 1.05-1.3 mol of H2O2, pref., 20-70 wt.% of active aq. H2O2 per 1 mol of the tertiary amine are reacted in the presence of a synergistic combination of accelerators formed by adding ascorbic acid and CO2 to a reaction mixture pref. at 3-90°C to obtain the objective compd. useful for a tableware detergent, a washing detergent or a fiber cloth softener. As the tertiary amine, a trialkylamine like a 6-22C alkyl di-1-2C alkylamine such as octyldimethylamine, decyldimethylamine, dodecylidimethylamine or tetradecylamine is designated. The pref. conc. of ascorbic acid is 0.05-5 wt.% and CO2 is set to a pressure of 1-500 psig.
