Abstract

A method for producing a shell catalyst which is suitable for the synthesis of alkenyl carboxylic acid esters, in particular for producing vinyl acetate monomer (VAM) from ethylene or allyl acetate monomer from propylene by means of oxy-acetylation. Also, 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 for producing alkenyl carboxylic acid esters, in particular vinyl acetate monomer (VAM) and allyl acetate monomer.
