The invention relates to a catalyst-composition for the oxychlorination of ethylene, containing a mixture of metal salts on a support, whereby the above-mentioned metal salts are applied to the support in such ratio proportions that the catalyst-composition comprises: a) 3 - 12 wt. % of copper as a copper salt, b) 0 - 3 wt. % of an alkaline earth metal as an alkaline earth metal salt, c) 0 - 3 wt. % of an alkaline metal as an alkaline metal salt, d) 0.001 - 0.1 wt. % preferably 0.005 - 0.05 wt.- %, of at least one metal selected from the group of ruthenium, rhodium, palladium, osmium, iridium and platinum and/or 0.0001 - 0.1 wt. % preferably 0.001 - 0.05 wt. % and gold, as a corresponding metal salt or tetrachlorogold acid, whereby all the weight percentages are in relation to the total weight of the catalyst including the support material. The invention also relates to a method for producing 1.2 dichlorethane for the oxychlorination of ethylene by catalysing the above mentioned catalyst-composition. |
