| Abstract: | The selective oxidation of cyclohexanol to cyclohexanone was studied systematically using WO3,Na2WO4·2H2O,Na9SbW9O33] and the prepared 9SbW9O33] as tungsten-based catalysts and H2O2 as oxidant. The influence of the amount of substance ratio of the starting materials,the temperature and the reaction time were improved.9SbW9O33] showed the highest catalytic activity.The conversion of cyclohexanol reaches 97.4% and the selectivity to cyclohexanone is 99.7% within 2 hours,while the temperature is 80 ℃ and the ratio of n(H2O2)∶n(cyclohexanol)∶n(9SbW9O33]) is 75∶50∶0.06. |
