Tungsten-based catalyst Sn-doped was developed which was employed to catalyze the synthesis of adipic acid from cyclohexanone oxidized. The effects of various factors such as catalyst dosage,30% hy-drogen peroxide dosage,reaction time,acidic ligand,and reusability of the catalyst were all investigated. The results indicated that preparation catalyst condition indicated n(W): n(Sn)= 1. 8: 1,calcinating at 500 ℃ for 4 h. The optimal reaction conditions were that 100 mmol cyclohexanone,50 mL 30% H2 O2 , 1. 0 g catalyst SnO2 / WO3 ,the yield of adipic acid could reach 78. 4% . The catalyst possesses advantages of highly active,easily to operate. It also can be reused to a certain extent.
