METHOD FOR PREPARING 1,2-DICHLOROETHANE
Document Type and Number:
WIPO Patent Application WO/2023/178541
Kind Code:
A1
Abstract:
Disclosed in the present application is a method for preparing 1,2-dichloroethane. The method comprises reacting raw materials containing ethylene glycol diacetate and hydrogen chloride in the presence of a catalyst to obtain 1,2-dichloroethane. By means of the method, ethylene glycol diacetate can be efficiently converted into 1,2-dichloroethane, and the yield of 1,2-dichloroethane is very high.
