TH32608A - How to prepare for vinyl acetate catalyst By using alkali methosolate - Google Patents

Abstract

DC60 (10/06/40) A method for preparing a catalyst using the synthesis of unsaturated ester. Where the catalytic carrier is Soaked with dissolved palladium salt and additives. The poured gold was followed by precipitation of dissolved palladium salt. And dissolved gold compounds To the insoluble palladium and gold compounds by fixing the compound mixture With alkali methanolate, platinum and platinum compounds are reduced to metal, palladium, and gold with ethylene or hydrazine. Soaked with alkali. Tol-acetate, for example Potassium acetate Catalyst used Synthetic unsaturated ester can be used to synthesize vinyl acetate with severe final product reduction. A method for preparing a catalyst using the synthesis of unsaturated estor in which the catalyst is treated. Water-soluble palladium salt and water-soluble gold compounds were followed by precipitation of soluble palladium salt. And dissolved gold compounds Into a can of palladium and Water insoluble gold compound by fixing the splice mixture. With alkali methosolate The fixed palladium and gold compounds were reduced to palladium metal and gold with ethylene or hydrazine, followed by an alkali-impregnating carrier. Tol-acetate, for example Potassium acetate Catalyst used Synthetic unsaturated ester can be used to synthesize vinyl acetate with severe final product reduction.
