FIELD: industrial organic synthesis catalysts.
SUBSTANCE: invention provides catalyst containing vanadium, at least one alkali metal compound, and, if necessary, one or several promoters on porous carrier, said catalyst being prepared by applying at least one palladium compound onto porous carrier, in particular titanium dioxide, followed by reduction at 300-500°C. According to invention, before or after reduction, at least one alkali metal compound and, if necessary, one or several promoters are applied. Catalyst is used in gas-phase production of vinyl acetate from ethylene, aqueous, and oxygen or oxygen-containing gases.
EFFECT: increased selectivity and productivity of catalyst.
