A catalyst for the oxychlorination of ethylene to 1,2-dichloroethane is prepared by impregnating a gamma -alumina support with a magnesium salt, drying the product, and impregnating the product with a copper salt, preferably together with a lithium salt. The catalyst preferably contains 0.1 to 5% magnesium, 2 to 10% copper and 0 to 5% lithium, by weight, and is particularly effective in oxygen-based processes. |
