ABSTRACT:
Catalysts for oxychlorination of ethylene to 1,2-dichloroethane, comprising compounds of copper and magnesium supported on alumina, in which the copper, expressed as metal, is present in an amount of 7 to 12% by weight and the Mg/Cu ratio is 0.05 to 1, and wherein the ratio between the concentration of copper provided by the Al/Cu ratio at the surface and that provided by the Al/Cu ratio in the entire particle of the catalyst is from 0.8 to 1.3.
