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.

在Au / TS-1催化剂上，在H2和O2存在下，将丙烯直接气相氧化为丙酮。

据报道，通过在A2负载的TS-1催化剂（Au / TS-1）下在H2和O2存在下丙烯进行气相氧化，可以制得一种新的丙酮制备方法。通过将反应温度提高到280 oC，Au / TS-1可以以11.6％的产率催化11.6％的丙烯生成丙酮和8.2％的丙酮。丙酮起源于环氧丙烷异构化，这主要归因于路易斯碱的表面和较高的反应温度。此外，小的金纳米颗粒尺寸促进了反应。
