Improved procedure for the reintroduction of 1,2 - DICHLOROETHANE not transformed from the Dissociation of 1, - DICHLOROETHANE in the process for the production of Vinyl Chloride

摘要

An improved process for removal of chloroprene from 1,2-dichloroethane recovered unconverted from the effluent of 1,2-dichloroethane pyrolysis. The chloroprene is chlorinated with chlorine in the presence of o- or m-cresol or a chlorinated derivative thereof, and the excess chlorine from this step is removed by reaction with ethylene.
