FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing a catalyst or procatalyst, to catalysts for producing alkenylalkanoates and a method of producing alkenylalkanoates. A method is described for making a catalyst or procatalyst, suitable for use together to produce alkenylalkanoates, involving bringing palladium-, gold- and rhodium-containing precursors into contact with carrier material, calcination in a non-reducing atmosphere, reduction of the palladium-, gold- and rhodium-containing precursors as a result of bringing reducing medium into contact with carrier material and bringing acetate of an alkali metal into contact with reduced carrier material. Described is a catalyst composition for producing alkenylalkanoates which contains: carrier material, which contains at least palladium, rhodium, gold and acetate of alkali metal which are brought into contact with the carrier material, obtaining a catalyst or procatalyst for producing alkenylalkanoates, where at least palladium and rhodium are calcined in a non-reducing atmosphere. Also described is a method of producing alkenylalkanoates, involving bringing initial material, which contains alkene, alkane acid and oxidising agent into contact with the above described catalyst or procatalyst.

EFFECT: increased activity and selectivity of catalyst for producing alkenylalkanoates.
