ABSTRACT:
The invention relates to Pd/K/Au, Pd/K/Ba or Pd/K/Cd supported catalysts built up in the form of an outer layer, the production thereof and also the use thereof for preparing vinyl acetate from ethylene, acetic acid and oxygen in the gas phase. The catalysts specified are produced by impregnating the support particles, while mixing intimately, with a solution of salts of the corresponding elements and then drying the support particles immediately, with the dynamic viscosity of the solution being at least 0.003 Pa.s and the solution volume in impregnation being from 5 to 80% of the pore volume of the support particles.
