Abstract In order to solve the problem of excess amount of chromium residues and acidic water produced by traditional synthetic technology, a new green catalytic synthesis process for the catalytic oxidative dehydrogenation of trans-4-acetamidocyclohexanol to 4-acetamidocyclohexanone is studied in this paper. The effect factors for the catalytic reaction in liquid phase by using 30% H2O2 as oxygenate were investigated. The experimental results indicated that, WO3 is the main catalytic active component and silica is a better carrier for the reaction; the yield to 4-acetamidocyclohexanone could be reached to about 96% by using the catalyst of 25%WO3/SiO2 as the molar ratio of H2O2 to trans-4-acetamidocyclohexanol was 5.1 at 90 ℃ for 4 hours. This is an environment friendly process comparing to the traditional oxidation process by bichromate. However, the experimental results showed the active component WO3 would be lost greatly during the repeated process; the performance for the repeated use of the solid catalyst should be improved in the future.
