| Abstract: | Using H3PW12O40 as catalyst, adipic acid was synthesized from the oxidation of cyclohexanone by 30% H2O2. Influences of dosage of H3PW12O40, reaction temperature, volume of hydrogen peroxide and dosage of KHSO4 were also discussed. Experimental results show： H3PW12O40 is a good catalyst for synthesis of adipic acid. The optimum conditions are that n（cyclohexene） ： n（ H2O2 ） ： n（ H3PW12O40 ） ： n（ KHSO4 ） = 100： 388： 0. 035：0.74 （fixed cyclohexanone 0.10 mol, dosage of H3PW12O40 is 0.1 g, volume of H2O2 is 40 mL, dosage of KHSO4 is 0. 1 g） ,reaction temperature is 100 ℃, reaction time is 6 h. Under the optimum conditions, the yield of adipic acid is 49.5%. |
