METHOD FOR PRODUCING A SHELL CATALYST, THE CATALYST AND ITS USE FOR THE SYNTHESIS OF ALKENYL CARBOXYLIC ESTERS

摘要

The present invention relates to a method for producing a shell catalyst which is suitable for the synthesis of alkenyl carboxylic acid esters, comprising first applying an acetate to a support body, followed by applying Pd and Au precursor compounds and subsequent reducing of the metal components to the elemetal metals. The present invention also relates to a shell catalyst that can be obtained by the method according to the invention as well as the use of the shell catalyst produced using the method according to the invention for producing alkenyl carboxylic acid esters, in particular vinyl acetate monomers (VAM) from ethylene and allyl acetate monomers from propylene by means of oxy-acetylation.
