Abstract:Adipic acid was synthesized by cyclohexanone oxidation with 30%w(H_2O_2) catalyzed with self-made phosphotungstic acid/silicon dioxide in absence of organic solvent and phase transfer catalyst under microwave irradiation.The influential factors on the reaction were discussed by orthogonal and simple fact experiments.And the optimal process conditions were decided. The results showed that the yield of adipic acid reached 73.24%under the conditions as followed:phosphotungstic acid loading 30%,1.20 g phosphotungstic acid/silicon dioxide,0.18 g oxalic acid,32.0 mL H_2O_2,reaction temperature 100℃,microwave power 400 W,reaction time 4.0 h;and the adipic acid yield was still 50.42%while repeatedly using the catalyst 5 times.
Keywords:supported  phosphotungstic acid  adipic acid  cyclohexanone  microwave  irradiation
