| 摘要: 以三乙氧基硅基苯((C2H5O)3Si-Ph，（(triethoxysilyl)benzene，TESB)以及正硅酸乙酯（TEOS）的混合液为硅源，以溴代十六烷基吡啶(CPBr)为模板剂，在HCl介质中合成了苯官能化的有机-无机杂化介孔分子筛MCM-41。对合成的分子筛用FT-IR、PXRD、TEM、N2吸附-脱附等手段进行了表征。结果表明，合成的苯官能化的有机-无机杂化介孔分子筛具有良好的介孔孔道结构。用三甲基氯硅烷对分子筛表面的Si-OH进行了封端处理，用氯磺酸对合成的苯官能化的有机-无机杂化介孔分子筛进行了磺酰化，并与各种二胺进行了反应。 |

| Abstract: Benzene functionalized organic-inorganic hybrid mesoporous molecular sieve of MCM-41 type was synthesized by co-condensation of (triethoxysilyl)benzene (TESB) and tetraethoxysilane (TEOS) using cetyl pyridine bromide (CPBr) as template. The products were characterized by means of FT-IR, Powder XRD and N2 adsorption/desorption isotherm. The prepared organosilica was with hexagonal structure and mesoporous pore size of 2.8 nm. The terminal Si-OH on organosilica surface was capped by trimetyl chlorosilane before sulfonylation to benzene groups stretching out of the organosilica surface. Diamines were anchored to organosilica by reaction with sulfonylated benzene groups in organosilica. |
