FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing catalysts and use thereof. Described is a method of producing a palladium-gold catalyst on a support, involving: (a) increasing mercury penetration volume of a titanium dioxide support to 0.31 ml/g or higher by mixing two titanium dioxides with different particle size or by mixing sintered titanium dioxide with non-sintered titanium dioxide or by mixing spray dried titanium dioxide with non-spray dried titanium dioxide, and saturating the support with a palladium salt, a gold salt and, optionally, an alkali metal or ammonium compound; and (b) reducing the saturated support to obtain a palladium-gold catalyst on a support. Described is a method of producing vinyl acetate, involving oxidation of ethylene in the presence of acetic acid and the palladium-gold catalyst described above.

EFFECT: described palladium-gold catalysts on supports have high activity during acetoxylation.
