摘　　要：在无相转移催化剂的条件下 ,用Na2 WO4·2H2 O或H7[P(W2 O7) 6]·xH2 O为催化剂 ,3 0 %H2 O2 可以将环己酮高产率地氧化成己二酸 .钨催化剂用量、反应液酸度对反应结果有着重要的影响 .当钨原子与环己酮的摩尔比为 1 5 % ,反应初始液的pH值为 1 0时 ,己二酸的得率可达 82 % ;Cyclohexanone can be directly oxidized to adipic acid with 30% H 2O 2 using Na 2WO 4·2H 2O or H 7[P-(W 2O 7) 6]·xH 2O 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 of the reaction mixture is 1.0 and 1.5% tungstate catalyst is used, 82% yield of adipic acid can be obtained. The catalyst can be recycled easily with no loss of the activity.
