FREMGANGSMAATE TIL RENSNING FOER RESIRKULERINGEN AV UOMSATT 1,2-DIKLORETAN FRA VINYLKLORIDFREMSTILLINGEN VED 1,2-DIKLORETANSPALTNING

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 i...

Zusammenfassung: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.
