METHOD FOR PRODUCTION OF ALKYLDIMETHYL(BENZYL)AMMONIUM CHLORIDES Russian patent published in 2003 - IPC

FIELD: industrial organic synthesis. SUBSTANCE: invention, in particular, relates to production of alkyldimethyl(benzyl)ammonium chlorides based on dodecyldimethyl(benzyl)- and tetradecyldimethyl(benzyl)ammonium chlorides possessing disinfecting properties and which may be used for manufacturing household chemical goods. Method consists in reaction of (i) mixture of alkyldimethylamines containing dodecyldimethylamine and tetradecyldimethylamine obtained by rectification purification of crude mixture of tertiary amines with (ii) benzyl chloride taken at (1)/(ii) weight ratio (1.57- 1.87):1. Reaction proceeds at elevated temperature and stirring. Desirable benzyl chloride is purified by distillation at atmospheric pressure and temperature 177-178 C. EFFECT: enabled production of effective, inexpensive, and low-toxic disinfectant required no further purification. 2 cl, 1 dwg, 3 tbl, 5 ex
