ABSTRACT:
The invention refers to a process for the production of high-purity 1,2-dichloroethane from dissolved chlorine and dissolved ethylene, which are brought into contact with each other in a circulating liquid reaction fluid, which mainly consists of 1,2-dichlorethane and a catalyst and flows through at least one vertically arranged loop-type reaction section, both legs of the loop being connected to an overhead degassing vessel from where the reaction product is withdrawn either in gaseous or in liquid state or in both gaseous and liquid state, and numerous admixing sections being arranged in the leg of the loop in which the liquid rises, and each of these admixing sections having one upstream feed point for dissolved or gaseous ethylene and one downstream feed point for dissolved chlorine and, if required, the admixing sections featuring static mixers.
