| 摘 要： | 基于水热合成法制备的Fe-MCM-22分子筛，实验考察了铁离子负载量对N2O为氧化剂的苯一步氧化制苯酚反应的影响．X射线粉末衍射（XRD）、N2吸／脱附和程序升温氨脱附法（NH3-TPD）表征结果表明，Fe-MCM-22分子筛具有较高的比表面积和规整的孔道结构，且铁杂原子以同晶替代的方式引入MCM-22分子筛骨架．活性评价结果表明，Fe-MCM-22分子筛活性与负载的铁离子含量有关，当n（Fe）／n（Al）=1：9时，苯转化率达到最高的18．6％．

| Abstract: | The effect of Fe-ions loading on Fe-MCM-22 zeolites prepared through hydrothermal synthesis method on the reaction of one-step oxidation of benzene to phenol with N2O was studied.The results of XRD,N2 adsorption/desorption and NH3-TPD indicated that Fe-MCM-22 zeolites had the higher special surface area and the ordered channel structure.Fe-ions loaded in the framework of MCM-22 through isomorphous institution.The results of activity evaluation showed that the activity of Fe-MCM-22 zeolites was related to the Fe-ions loading.The benzene conversion was 18.6% when the mole ratio Fe/Al of the sample was 1∶9. |
