【摘要】 以正硅酸乙酯为硅源,AlCl3和Al(NO3)3为铝源,采用一步法合成了硅／铝比为20的AlCl3／双模型介孔分子筛和Al(NO3)3／双模型介孔分子筛。采用XRD、NH3程序升温脱附、低温N2吸附-脱附等方法表征了所合成分子筛的物化性能,从而考察了铝源对分了筛的结构、酸性、热稳定性及水热稳定性的影响。同时以萘与异丙醇的烷基化反应作为模型反应,初探了铝源对分子筛催化性能的影响。更多还原

【Abstract】 By using TEOS as silicon source, and aluminum chloride anhydrous and aluminum nitrate as aluminum source, the AlCl3 and Al(NO3)3 bimodel mesoporous molecular sieves with the Si to Al molar ratio of 20 were prepared. The effects of aluminum source on the structure, acidity, thermal stability and hydrothermal stability of the molecular sieves were studied by means of XRD, NH3-TPD. Meanwhile, their catalytic performance for the alkalation of isopropanol with naphthalene was investigated.更多还原
