  • Preparation of 1,2-dichloroethane by oxychlorination of ethylene over a copper-containing supported catalyst
    Patent number: 4740644
    Abstract: 1,2-Dichloroethane is prepared by oxychlorination of ethylene in the presence of a catalyst which contains, on a conventional carrier, copper(II) chloride in a concentration such that the amount of copper ions is from 1 to 20% by weight, based on the total weight of the catalyst, by a process in which the catalyst is obtained by impregnating the carrier with an aqueous solution which contains copper(II) chloride and hydrogen chloride in amounts such that the weight ratio of copper ions to hydrogen chloride is from 13:1 to 130:1.

  • Supported catalyst containing copper and alkali metals
    Patent number: 4382021
    Abstract: A supported catalyst containing copper and alkali metals, wherein the content of copper is from 1.0 to 12% by weight, based on total catalyst and expressed as metal, and the total content of the alkali metals potassium, lithium and sodium is from 0.3 to 9% by weight, based on total catalyst.The novel catalyst is useful for the preparation of 1,2-dichloroethane by oxychlorination of ethylene.
