Cyclohexanone can be directly oxidized to adipic acid with 30% H2O2 using Na2WO4·2H2O or H7[P-(W2O7)6xH2O as a catalyst without any phase transfer catalyst. The quantity of tungstate catalysts and the acidity of reaction mixture affect the results greatly. It is found that when pH ofthe reaction mixture is 1.0 and 1.5% tungstate catalyst is used, 82% yield ofadipic acid can be obtained. The catalyst can be recycled easily with no loss ofthe activity.

Key words: cyclohexanone, sodium tungstate, phosphotungstic acid, peroxide hydrogen
