| description | This invention provides a microemulsion process for the preparation of a supported palladium-gold catalyst for the production of vinyl acetate from ethylene, acetic acid and oxygen. A preferred catalyst composition has a content of colloidal palladium-gold alloy uniformly distributed on an alpha -alumina support. An invention catalyst exhibits a sustained level of selectivity for vinyl acetate production over an extended processing period. |
