ABSTRACT:
Alumina is used as a support for the CuCl2 catalyst and as a diluent in the oxychlorination of ethylene. When a low surface area alumina, e.g. high purity alpha-alumina, is used as diluent for the reaction, reduced oxidation and less chlorinated by-products are achieved. Alternatively, the alumina used as the catalyst support, e.g. a gamma-alumina which has a high surface area and higher amounts of impurities, can be used as diluent if it is impregnated with an alkali metal ion, e.g K+ ion, which is usually employed as a salt.
