MCM-41 Zeolite Supported Phosphotungstic Acid-Catalyzed Oxidation of HydrogenPeroxide Cyclohexanone/Cyclohexanol Synthesis of Adipic Acid

In the absence of solvent,phase transfer catalyst without conditions, with phosphotungstic acid as a catalyst,using MCM-41 zeolite as a catalyst carrier,30% hydrogen peroxide as the source of oxygen.under certain temperature can be cyclohexanol / cyclohexanone mixture into adipic acid oxidation.The 30% hydrogen peroxide amount,the reaction time,temperature,amount of catalyst,acid on the production of adipic acid,catalyst recovery and reuse were discussed.The results showed: when MCM-41 zeolite load of 80% phosphotungstic acid catalyst for 7h,Adipic Acid maximum production rate is as high as 89.17%.
