| 摘 要： | 采用溶胶一凝胶法制备了二氧化硅负载硅钨钼酸催化剂．以二氧化硅负载硅钨钼酸（H4SiW6M06040／SiO2）为催化剂，30％H202为氧源，催化氧化环己酮合成己二酸．探讨H4SiW6Mo6O40／SiO2对氧化反应的催化活性，较系统地研究了二氧化硅负载硅钨钼酸用量、反应温度、H。02用量、反应时间等因素对产物收率的影响．实验表明：H4SiW6Mo6O40／SiO2是合成己二酸的良好催化剂；在n（环日酮）：n（H2O2）：n（H4SiW6Mo6O40／SiO2）=100：198：0．124，反应温度为110℃，反应时间3．5h的最佳条件下，己二酸的收率可达86．7％．

| 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%. |
