Abstract:A new environmental friendly catalyst,H4SiW6Mo6O40/SiO2 was prepared by Sol-gel method. Using H4 SiW6 M06 O40/SiOz as catalyst, adipic acid was synthesized from the oxidation of cyclohexanone by 30% H2 02. Influences of dosage of H4 SiW6 M06 O40/SIO2, reaction temperature, volume of hydrogen peroxide and reaction time were also discussed. Experimental results were shown that.H4SiW6Mo6O40/SiO2 was a good catalyst for synthesis of adipic acid. When n(cyclohexene):n(H2O2) : n(H4SiW6Mo6O40/SiO2) = 100 : 198 : 0.124, reaction temperature was 110 ℃ and reaction time was 3. 5 h, under the optimum conditions, the yield of adipic acid was 86.7%.
Keywords:H4SiW6Mo6O40/SiO2  catalysis  cyclohexanone  adipic acid
