PROCESS FOR THE RECYCLING UNREACTED 1, 2- DICHLOROETHANE FROM 1, 2-DICHLOROETHANE CRACKING

PROCESS FOR THE RECYCLING UNREACTED 1, 2- DICHLOROETHANE FROM 1, 2-DICHLOROETHANE CRACKING

In the production of vinyl chloride by pyrolysis of 1,2-dichloro ethane on an industrial scale 1-chloro-butadiene-1,3 or 2-chloro butadiene-1,3 is formed. When recycling non-reacted 1,2-dichloro ethane to the pyrolysis sector 1- or 2- chloro-butadiene-1,3 must be removed. According to the invention...

Zusammenfassung:In the production of vinyl chloride by pyrolysis of 1,2-dichloro ethane on an industrial scale 1-chloro-butadiene-1,3 or 2-chloro butadiene-1,3 is formed. When recycling non-reacted 1,2-dichloro ethane to the pyrolysis sector 1- or 2- chloro-butadiene-1,3 must be removed. According to the invention the undesired compounds can be removed by a chlorination step and a subsequent dechlorination step.
