Patent ID: 7671244

Claim:
A process for the production of 1,2-dichloroethane of high purity from dissolved chlorine and dissolved ethylene that come into contact with each other in the presence of a circulated liquid reaction agent, the agent primarily consisting essentially of 1,2-dichloroethane and a catalyst, using at least one reaction unit arranged vertically and designed as loop, the two leg sections of the loop communicating with a degassing vessel arranged above the unit, the degassing vessel serving for the withdrawal of the reaction product in gaseous or liquid form or in both forms, the feed points for chlorine and dissolved ethylene being located in the loop leg section in which the liquid ascends, any upstream feed point for ethylene being followed by a downstream feed point for dissolved chlorine, wherein any feed point for chlorine is followed by at least one feed point for liquid 1,2-dichloroethane, and the addition of liquid 1,2-dichloroethane takes place with so much kinetic energy that a thorough mixture of 1,2-dichloroethane, dissolved chlorine and ethylene is effected.
