<p>Disclosed is a method for oxychlorination of ethylene for pr eparation of 1,2-dichloroethane, consisting of that in reaction o f ethylene with the substance representing the source of chlorine and with the substance representing the source of oxygen in the oxychlorination reactor in the presence of a catalyst, the nature of which consists in that it is realized in the only reactor and ethylene is in this reaction present in the high molar margin ag ainst to chlorine. The suitable substance, representing the sourc e of chlorine, is hydrochloric acid, the suitable catalyst is a c atalyst, comprising the cupric chloride and molar excess of ethyl ene is in the advantageous method of realization in the range fro m 200 % to 700 %.</p> |
