Beschreibung
Zusammenfassung:	An oxychlorination catalyst is described which is constituted by porous particles of microspheroidal, or at least microcrystalline, alumina impregnated with cupric chloride and with the chloride of an alkali or alkaline-earth metal, in which the copper and the alkali or alkaline-earth metal are uniformly distributed over the entire surface area of the particles. The method for the preparation of the catalyst is also described. The catalyst enables oxychlorination of ethylene to dichloroethane to be achieved with improved fluodynamic behaviour of the fluidised catalytic bed and with improved conversions and selectivity towards the useful reaction product.
