| 摘 要： | 以过渡金属离子(Fe3+,Co2+,Ni2+,Cu2+,Zn2+,V5+,Mn2+)取代的Keggin型磷钼酸为催化剂、30%(质量分数)的H2O2溶液为氧化剂,环己烯经催化氧化合成了反-1,2-环己二醇。考察了催化剂的种类和用量、反应温度、反应时间和H2O2用量对环己烯氧化反应的影响。实验结果表明,Fe取代的Keggin型磷钼酸(H6PMo11FeO40)是环己烯氧化制反-1,2-环己二醇的高效催化剂。适宜的反应条件为:环己烯10mmol、n(H6PMo11FeO40)∶n(环己烯)=0.020、乙腈3mL、n(H2O2)∶n(环己烯)=1.5、反应温度55℃、反应时间8h。在此条件下,环己烯的转化率为98%,反-1,2-环己二醇的选择性为97%。用核磁共振及气相色谱-质谱联用仪对产物进行表征,结果显示产物为反-1,2-环己二醇。

| Abstract: | The catalytic oxidation of cyclohexene to trans-1,2-cyclohexanediol using hydrogen peroxide aqueous solution (mass fraction 30%) as oxidant and Keggin-phosphomolybdic acid mono-substituted by various transition metals (Fe3+, Co2+, Ni2+, Cu2+, Zn2+, V5+, Mn2+)as catalysts was investigated. The effects of catalyst type, catalyst dosage, reaction temperature, reaction time and amount of hydrogen peroxide aqueous solution on cyclohexene oxidation were studied.
