ABSTRACT:
The invention relates to improved Pd/K/Au, Pd/K/Ba and Pd/K/Cd supported catalysts, their preparation and their use for the preparation of vinyl acetate from ethylene, acetic acid and oxygen in the gas phase. The stated catalysts are prepared by atomizing a solution of corresponding metal salts by means of ultrasonics and then applying them in such limited amounts and within such a limited time to the carrier particles, and beginning to dry them, so that the catalytically active metal salts cannot penetrate into the carrier particles as far as the core but only into a larger or smaller outer part.
