Classification: C07C

Abstract:
A process for converting light by-products having a boiling point below 83.7.degree. C. formed during the thermal cracking of 1,2-dichloroethane (DCE), said process being characterized in that chlorination of the said light by-products is carried out directly after preparation of the 1,2-dichloroethane by direct chlorination of ethylene in a reaction zone, in the presence of 1,2-dichloroethane, catalyst and chlorine resulting from the preparation of the 1,2-dichloroethane without heavy by-products having a boiling point above 83.7.degree. C., at a temperature of between 20.degree. C. and 80.degree. C., and in a zone external of said reaction zone.
