| Abstract: | In this work,a serialof heteropolyoxometallateswith rare earth were synthesized and used in the synthesis of adipic acid from cyclohexanone. Their catalyticactivity was evaluated and the result showed that K_8H_3La(PW_(11)O_(39_)_2]·25H_2O isthe best of all catalystsbecause of its high catalyticactivity. It was also found that when the reaction time was 8h,a high yield of 71.9% of adipic acid can be obtained. Besides,the optimum reaction conditions were determined by examining the effect of reaction conditions such as reaction temperature,time,amount of cyclohexanone and H_2O_2,and catalyst dosage. |
