Abstract
A process for preparing a catalyst which process comprises the steps of: (a) introducing a Group 8 metal compound onto a carrier, (b) converting a first portion of the Group 8 metal compound on the carrier into metallic species in a liquid phase reaction, and (c) subsequently converting a further portion of the Group 8 metal compound on the carrier into metallic species in a gas phase reaction; a catalyst which is obtainable by this process; and a process for preparing an alkenyl carboxylate comprising reacting a mixture comprising an olefin, a carboxylic acid and oxygen in the presence of the catalyst.
