METHOD OF CHLORINE PURIFICATION AND PROCESS FOR PRODUCING 1,2-DICHLOROETHANE

摘要

Purification of chlorine by separation of nitrogen and oxygen from crude chlorine, containing nitrogen and oxygen, comprises contacting crude chlorine with 1,2-dichloroethane to absorb the chlorine. An independent claim is included for the production of 1,2-dichloroethane by reacting ethylene with chlorine in 1,2-dichloroethane containing chlorine.
