摘要/Abstract

摘要： 以正硅酸乙酯((C₂H₅)₄SiO₄)、水玻璃、硅溶胶为硅源,四丙基氢氧化铵(TPAOH),四丁基溴化铵(TBABr)、四乙基氢氧化铵(TEAOH)和1,6-己二胺(HDA)为模板剂,使用氯氧化锆(ZrOCl₂)为锆源首次合成了Zr-SiPentasil型分子筛,用X射线衍射、X射线电子探针、红外光谱等研究了它的结构,并在X射线衍射仪上用每阶梯0.01°的阶梯扫描方法测得Zr-SiPentasil型分子筛的晶胞参数,结果表明Zr进入分子筛的骨架,研究了此分子筛的晶体形貌、吸附性能、憎水性、热稳定性、比表面以及表面酸性等。

Abstract: Zr-Si pentasil type molecular sieve was synthesized with tetraethyl orthosilicate or water glass as the silica source and zirconium oxychloride as the zirconium source, and tetrapropylammonium hydroxide (TPAOH), 1, 6-hexandiamine (HDA), tetracthylammonium hydroxide (TEAOH) or tetrabutylammonium bromide (TBABr) as the templating agent. The structure of the molecular sieve has been studied by means of X-ray diffraction, X-ray electron probe and IR. The parameters of unit cell of Zr-Si pentasil type molecular sieve were obtained by step scanning procedure with step size of 0.01°(2θ) on X-ray diffractometer. The results indicate that Zr is introduced into framework. The ability of adsorption, thermal stability, specific surface and acidity for the molecular sieve were also studied.
