Adipic acid was synthesized from cyclohexanone by using 30 percent hydrogen peroxide as oxidant, sodium bisulfate as cocatalyst, in the presence of H4SiW12O40/ZrO2-Al2O3 as catalyst. The factors influencing the synthesis were discussed and the best reaction conditions were found out. The experiments show that:H4SiW12O40/ZrO2-Al2O3 catalyst is an excellent catalyst for the synthesis of adipic acid. The optimum conditions are as 0.10 mol fixed cyclohexanone, 2 g H4SiW6Mo6O40/SiO2, 50 mL H2O2, 0.05 g sodium bisulfate, 6 h reaction time. Under the optimum conditions, the yield of adipic acid is 78.7%.
