Abstract: A process for the preparation of vinyl acetate in the gas phase from ethylene, acetic acid and oxygen or oxygen-containing gases on a catalyst which contains palladium and/or its compounds, and also, if desired, additionally gold and/or gold compounds, and also alkali metal compounds as activators and, if desired, additionally cadmium compounds, on a support. The support consists of cylindrical particles having curved end surfaces. The support material is aerogenic SiO2 or an aerogenic SiO2-Al2O3 mixture having a surface area of 50-250 m /g and a pore volume of 0.4-1.2 ml/g, which is formed to at least 50 % of pores having a diameter of 50-200 Angströms. … …
