[2-하이드록시-3-(m-톨릴옥시)프로필]이소프로필암모늄클로라이드 C화학적 특성, 용도, 생산
Originator
Doberol,Boehringer, Ing.
Manufacturing Process
59 g (1 mol) of isopropylamine in 60 ml of water are added to a solution of 82
g (0.5 mol) of 3-(3'-methylphenoxy)propylene oxide (prepared from 3-methyl phenol and epichlorohydrin) in 400 ml of ethanol. After the exothermic
reaction has subsided, the mixture is heated for 2 hours at 60°C. After
distillation of the volatile components, the free base remains as a solid
residue. It is dissolved in hydrochloric acid the acid solution is extracted with
ether and then made alkaline with caustic soda solution. The base crystallizes
out and is dried over P2O5; 101.9 g (91.3% of theory) of 1-(isopropylamino)-
3-(m-tolyloxy)-2-propanol being obtained; it is recrystallized from ethyl
acetate/petroleum ether, and then has MP: 75-76°C. Upon addition of ethereal
hydrogen chloride to an alcoholic solution of the base, the hydrochloride
precipitates, and after recrystallization from alcohol/ether, has MP: 120-
121°C.
