摘要：
A novel process for the preparation of acetone is reported by gas-phase oxidation of propylene in the presence of H-2 and O-2 with Au supported TS-1 catalyst (Au/TS-1). By elevating the reaction temperature to 280 degrees C, Au/TS-1 catalyzes 11.6% propylene generating acetone with 70.6% selectivity, and 8.2% acetone in onepass yield. Acetone is originated from propylene oxide isomerization, which is mainly attributed to the surface of the Lewis base and high reaction temperature. Furthermore, small Au nanoparticle size promotes the reaction.
