Hydrochloric Acid → Trihydroxystearic Acid Ethyl Ester

참여 물질

반응 단계

3 kg of trihydroxystearic acid are suspended in 10 l of absolute ethanol. Hydrogen chloride gas is slowly introduced at room temperature whilst stirring, until the acid has almost completely dissolved. The alcoholic ester solutionh is freed of a slight residue by filtration; thereafter the ester is precipitated by pouring the alcoholic solution into a 10-fold volume of water. The ester is filtered off and dried. The excess ethanol is recovered from the filtrate by distillation.
