LAYERED CARRIER MATERIAL FOR CATALYST Russian patent published in 2010 - IPC B01J23/66 B01J37/25 B01J32/00 C07C67/55 C07C69/15 

FIELD: chemistry.

SUBSTANCE: present invention relates to catalysts, methods of preparing catalysts and methods of producing alkenyl alkanoates. A method is described for preparing a catalyst suitable for use in production of alkenyl alkanoates, involving: deposition of a first carrier material and binding agent on a second carrier material to obtain layered carrier material in form of particles with an inner and an outer layer, where catalyst components in form of palladium, gold or combinations thereof are contained in the outer layer of the layered carrier material. A catalyst is also described for producing alkenyl alkanoates, which contains: layered carrier material in form of particles with at least an outer layer containing a first carrier material and binding agent, and an inner layer containing a second carrier material, where the outer layer contains at least palladium combined with gold which is in contact with it to obtain the catalyst, where the inner layer essentially does not contain palladium and gold. A method is described for producing alkenyl alkanoates, involving: bringing raw material containing alkene, alkanoic acid and oxidising agent into contact with a catalyst prepared using the method described above.

EFFECT: improved production of alkenyl alkanoates, reduced amount of by-products and increased efficiency of production.
