Method for the production of vinyl acetate

Abstract

Abstract The process for the preparation of vinyl acetate is carried out in the gas phase by reacting ethylene, acetic acid and oxygen and/or oxygen-containing gases on a catalyst containing palladium and/or compounds thereof, and optionally additionally gold and/or gold compounds, and, as activators, alkali metal compounds, and optionally additionally cadmium compounds on a support. The support comprises SiO2 or SiO2/Al2O3 mixtures having a surface area of 50 - 250 m<2>/g and a pore volume of 0.4 - 1.2 ml/g, and has a particle size of from 4 to 9 mm. From 5 to 20% of the pore volume of the support is formed by pores having radii of from 200 to 3000 ANGSTROM ngstrom and from 50 to 90% of the pore volume is formed by pores having radii of from 70 to 100 ANGSTROM ngstrom.
