| titleOfInvention | Catalyst, process for preparing catalyst and process for preparing vinyl acetate using catalyst |
| abstract | The present invention provides a process for preparing a catalyst for preparing vinyl acetate from ethylene, acetic acid and oxygen or oxygen containing gas in gas phase. The catalyst comprises palladium and / or a compound thereof, gold and / or a compound thereof and also an alkali metal compound on the granular porous support,n n n a) the support is impregnated with soluble palladium and gold compounds,n n n b) converting the soluble palladium and gold compounds into insoluble palladium and gold compounds by adding an alkaline solution to the support,n n n c) reducing the insoluble palladium and gold compounds on the support with a reducing agent in the liquid or gas phase,n n n d) impregnating the support with at least one soluble alkali metal compound,n n n e) Finally, the support is prepared by drying at up to 150 ° C., wherein the catalyst is irradiated with microwaves before, during or after any of the steps of preparation steps a) to e). |
