| 摘 要： | 文章报道了一种利用甲苯二异氰酸酯（TDI）作桥连分子制备高氨基官能化介孔SBA－15分子筛的方法。首先，SBA－15表面的Si－OH与TD1分子中的一个－NCO基反应，然后，TD1分子中另一端未参与反应的－NCO基与乙二胺分子中的一个－NH2基反应，如此，－NH2被成功地嫁接到介孔SBA－15分子筛表面，用XRD、N2－吸脱附、FTIR和^29Si MA SNMR表征，结果表明，一NH2被成功引入到SBA－15分子筛表面，且材料具有良好的介孔结构。

| Abstract: | Surface NH2-functionalized SBA-15 mesoporous silica was synthesized by using toluene diisocyanate （TDI） as bridge molecule. Firstly, surface Si-OH of SBA-15 reacted with one NCO group of TDI molecular, and another unreacted -NCO group of TDI molecular reacted with one -NH2 group of ethylenediamine （EDA）. Then NH2- group was successfully attached to mesoporous SBA-15 surface. Identified by XRD, N2 adsorption/desorption analysis, FTIR and 29Si MAS NMR, the results showed that -NH2 were successfully attached to the surface of SBA-15, the materials has good mesoporous structure. |
