AI Technical Summary
Current methods for producing vinyl acetate catalysts using palladium, gold, and copper face challenges in achieving high selectivity and catalytic activity, with limitations in suppressing carbon dioxide by-product generation and optimizing metal distribution on the carrier.
A method involving simultaneous support of palladium, gold, and copper-containing compounds on a carrier with an alkali component, followed by reduction treatment and acetate impregnation, enhances the selectivity and activity of the catalyst by ensuring close proximity of gold to palladium and rapid hydrolysis of copper, leading to improved vinyl acetate production.
The method significantly improves the selectivity and catalytic activity of vinyl acetate production, achieving exceptionally high selectivity and maintaining high catalytic performance compared to conventional methods.
