    摘要: Methods for the catalytic production of vinyl acetate monomer from ethane, ethylene or an ethanelethylene mixture using a first catalyst containing MoVNbPd, MoVLaPdbX (where X is Al, Ga, Ge or Si) or MoVNbX (where X is P, B, Hf, Te, As or mixtures thereof) in the first step of oxidation and using a conventional VAM catalyst for the second step. The method produces high yields to acetic acid and vinyl acetate without the coproduction of carbon monoxide. Furthermore, the ethylene and acetic acid produced in the first step may be utilized in the second step for VAM production.
