Beschreibung
Zusammenfassung:	Catalysts for the oxychlorination of ethylene to 1,2-dichloroethylene, comprising compounds of Cu and Mg supported on alumina, in which the copper content, expressed as Cu, is 2 to 8% by weight, the Mg/Cu atomic ratio is from 1.2 to 2.5, the specific surface of the catalyst is from 30 to 130m /g, and with distribution of the copper atoms more inside the particle of the catalyst than on the surface (layer with a thickness of 20-30 ANGSTROM ) and of the magnesium atoms more on the surface (20-30 ANGSTROM layer) than inside the particle.
