Abstract:A novel process for the preparation of acetone is reported by gas-phase oxidation of propylene in the
presence of H2 and O2 with Au supported TS-1 catalyst (Au/TS-1). By elevating the reaction temperature to
280 oC, 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.
