ABSTRACT:
One aspect of the present invention relates to a method of making vinyl acetate monomer, involving contacting reactant gases with a catalyst containing palladium, gold and a support in the presence of clean steam, the clean steam present from about 2 to about 10 psia, with the proviso that the support does not contain alumina or zinc oxide and the support is not treated with a sulfur containing compound. For example, the method of making vinyl acetate monomer may involve the reaction scheme:
