Abstract
A catalyst particularly useful in the preparation of unsaturated esters such as the reaction of ethylene, oxygen and acetic acid in a vapor phase to form vinyl acetate. The catalyst comprises a honeycomb carrier coated with silica and containing palladium and gold throughout the silica coat. Such catalysts show reduced pressure drop and a high space time yield for vinyl acetate.
