FIELD: industrial organic synthesis and catalysts. SUBSTANCE: catalyst contains catalyst carrier, palladium, heteropolyacid, at least one acetic acid production catalyst promoter, and at least one vinyl acetate production promoter selected from group comprising cadmium acetate, gold, copper, and nickel. Vinyl acetate is produced from ethylene and oxygen-containing gas in presence of this catalyst in a single-stage process. EFFECT: increased catalyst selectivity. 11 cl, 4 ex
