ABSTRACT:
An oxychlorination catalyst precursor is described which is constituted by porous microspheroidal alumina particles impregnated with 3 to 7% by weight of cupric chloride (expressed in terms of the copper metal) and containing from 0.5 to 2% by weight of water, in which the copper is uniformly distributed over the entire surface area of the particles with a degree of non-uniformity not greater than .+-.7%.
A process for the preparation of such a catalyst precursor is also described.
The precursor is activated to give a catalyst which is readily fluidizable and which enables the oxychlorination of ethylene to dichloroethane to be carried out with high activity and selectivity values.
