1. Catalyst comprising palladium, gold and alkali metal acetate as catalytically active components on a support, characterized in that the catalyst is modified by means of titanium, iron, lanthanum, cerium, yttrium andor molybdenum or oxides thereof.
2. Process for producing the catalyst according to claim 1, characterized in that the support is impregnated with a salt of at least one doping component, calcined and subsequently impregnated with the catalytically active component or the support material is mixed with an oxide of the doping component, shaped and subsequently impregnated with the catalytically active components.
3. Process according to claim 2, characterized in that the doping component is applied to the support simultaneously with the catalytically active component.
4. A process for preparing vinyl acetate monomer comprising carrying a reaction to produce vinyl acetate in the presence of the catalyst of claim 1.
5. The catalyst according to claim 1 wherein the support is aluminosilicate, titanium dioxide, or silicon dioxide.
The claims below are in addition to those above.
