摘　　要：通过煅烧法制备出几种金属氧化物、复合金属氧化物催化剂,在催化、30%(质量分数)的H_2O_2氧化环己酮制备ε-己内酯的氧化反应中,将其与商业级金属氧化物催化剂进行对比.实验结果表明,商业级MgO具有更好的收率、低廉的价格,在n(H_2O_2)∶n(MgO)∶n(环己酮)为9∶0.6∶1、环己酮的量为0.1 mol、乙腈用量为60 mL、反应温度70℃、反应时间为6 h的条件下,ε-己内酯的收率达到73.7%.We prepared a series of metal oxides and composite metal oxides catalysts by calcination method andcompared it with commercial metal oxide which prepared of ε-caprolactone by cyclohexanon oxidation. The resultsshowed that commercial MgO had the better yield and cheap price. When the n(H_2O_2)∶n(MgO)∶n(cyclohexanone)was 9∶0.6∶1,the reaction temperature was 70 degree,the time was 6 hour,and the yield of ε-caprolactone reached73.7%.
