There is a solution for the production of vinyl acetate here in ethylene, acetic acid and acid gas, or with oxygen-containing gas, in addition to the formation of catalysts, the catalyst contains palladium. and / or its compound, gold and / or its compounds, as well as alkali metal compounds on the support. The catalyst comprises boron or boron compounds. It is susceptible to the production of this catalyst in that it is impregnated with soluble palladium and gold compounds, which are converted with an alkaline solution to an insoluble compound, which is reduced by a reducing agent. It is then washed and dried and then impregnated with a soluble alkali metal compound and finally dried at most 150 degC. The process for producing vinyl acetate using this catalyst. \ T |
