Beschreibung
Zusammenfassung:	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 /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.
