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.
Claims1
A supported catalyst which is useful for the oxychlorination of ethylene and which comprises:
