英文摘要：

Cyclohexanol was oxidized to cyclohexanone under a mild condition with Na2WO4. 2H2O as catalyst, H2O2 as oxidizing agent and ionic liquids as phase transfer catalysts. The effects of different phase transfer catalysts, the amount of catalyst Na2WO4.2H2O , the amount of H2O02, reaction time, and temperature on the oxidation of cyclohexanol also were studied. The results showed that ionic liquids （[ C16mim] HSO4 and [ C14mim] HSO4） were a kind of efficient phase transfer catalysts for the oxidation of eyelohexanol. The conversion of eyclohexanol and the selectivity to cyclohexanone were about 100% and 99% respectively under optimum reaction conditions （cyclohexanol 0.1 mol, 30% H20225 mL, phase transfer catalyst 4.0 mmol, catalyst Na2WO4 2H2O 5.5 mmol, 90℃ for 50 min）. The activity of phase transfer catalysts still keep high stability after reused 5 times.
