Abstract: The liquid aluminium trichloride-hydrocarbon complex formed from a catalytic process is reactivated by instantaneously vaporizing it under conditions such as to form no more than 25 wt. percent of normally gaseous products, e.g., at atmospheric pressure and 300* to 500* C, and the vaporized products are condensed and the normally liquid catalytic products are recovered. The complex can be used for catalysing the alkylation of benzene with propylene tetramer.

Abstract: Ethylene oxidation catalysts are prepared by depositing silver oxide and metallic or oxide platinum, palladium or gold on an inert support, treating the support with specified organic acids such as lactic acid in aqueous solution and then heat treating.
