Direct catalytic oxidation of cyclohexanol to cyclohexanone with aqueous hydrogen peroxide using hexadecyl trimethyl ammonium decatungstate catalyst was performed with 82.4%～89.1% yields and 89.6%～96.4% of cyclohexanol conversion. The experimental results indicated that the catalyst was favorable to oxygen transfer from hydrogen peroxide to the substrate, and cyclohexanol could be oxidized efficiently to cyclohexanone with hydrogen peroxide.
