摘要: 分别以1,2-双(三乙氧基硅基)乙烷(BTESE)、1,2-双(三乙氧基硅基)乙烯(BTESEE)和苯基三乙氧基硅烷(PTES)为硅源, 通过一步法直接合成有机硅骨架修饰的磷酸铝分子筛VPI-5. 系统考察了各反应参数对产物结构与性质的影响, 并对产物的结构进行了表征. 表征结果表明, 有机基团通过硅原子被引入到分子筛骨架中. 有机基团的引入增加了分子筛的亲油性, 并且不同的有机基团对分子筛的亲油性的提高程度不同.

Abstract: Using 1,2-bis(triethoxysilyl)ethane(BTESE), 1,2-bis(triethoxysilyl)ethylene(BTESEE), and phenyltriethoxysilane(PTES)   as silicon sources, organosilica functionalized Si-VPI-5 molecular sieves were synthesized under hydrothermal conditions and the effects of reaction conditions were investigated. Structural characterizations show that the Si atoms with organic groups are introduced into the molecular sieve frameworks. The introduction of organic groups increases the hydrophobicity of the molecular sieves, and the introduction of different organic groups leads to different increase degrees of the hydrophobicity  on the  molecular sieves.
