Abstract RU 2422201 C1

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry and specifically to chemistry of catalytic processes and can be used in production of a vinyl acetate synthesis catalyst. Described is a method of producing a catalyst for synthesis of vinyl acetate, which contains gold and palladium, involving saturation of a support with gold and palladium salt solutions, followed by reducing gold and palladium. The reducing agent used to reduce gold and palladium is perhydro-(1,3,5-dithiazin)-5-yl-methane of formula C4H7NS2, which is taken in amount of not less than 200% of the total weight of the gold and palladium. Thermal treatment is then carried out at temperature 500-600°C for 2 hours.

EFFECT: method increases output of vinyl acetate.
