| Abstract: | Adipic acid was synthesized from cyclohexanene by hydrogen peroxide oxidation using phosphotungstic acid with Dawson structure as catalyst in absence of organic solvent and phase transfer.The effects of the catalyst amount,hydrogen peroxide amount,reaction time and temperature on the reaction were discussed.The results showed that the the yield of adipic acid could be 76.6% under the conditions as followed: the mole ratio of cyclohexanene,hydrogen peroxide and catalyst of 1005000.2,reaction temperature 100℃,reaction time 5 h.The reaction complied with the cascade reaction mechanism. |
