PROCESS FOR PREPARING DICHLOROETHANE AND APPARATUS USED FOR THE SAME

摘要

A process for preparing dichloroethane according to a two-stage oxychlorination reaction. The catalyst is oxidized in a reactor which is separated from a reactor where ethylene is chlorinated. The catalyst is circulated between an oxidation reactor and a chlorination reactor through a catalyst recovering line and a catalyst feed line. Preferably, an inner pressure of the oxidation reactor is higher than that of the chlorination reactor to avoid the formation of a flammable mixture.
