摘要：
The present invention is directed to a process for preparing 1,2-dichloroethane by reacting ethene with hydrogen chloride and oxygen over a copper-containing fluidized-bed catalyst. The discharge of the catalyst from the reactor per se is avoided if the catalyst is virtually completely retained in the upper part of the reactor by means of superfine filtration.
