【摘要】 以有机硅CH₃Si（OC₂H₅）₃和NH₂（CH₂）₃Si（OC₂H₅）₃为交联剂,对层状化合物α-Zr（HPO₄）₂·H₂O进行交联,经灼烧分别得到2种不同层间距的层柱型分子筛SiO₂-Zr（HPO₄）₂。用XRD、GC、NMR等方法对交联反应过程进行了研究,结果表明,交联剂在反应过程中发生水解、缩聚。某种聚合态硅选择性地嵌入α-Zr（HPO₄）₂·H₂O层间。更多还原

【Abstract】 Two new Zeolite like materials, SiO2-Zr(HPO4)2( Ⅰ ) and SiO2-Zr(HPO4)2( Ⅱ ), were synthesized by reacting the cross-liking agents of CH3Si(OC2H5)3 and NH2(CH2)3Si(OC2H5)3 with layer compound of a-Zr(HPO4)2 . H2O . The reactions produced two types of SiO2-Zr(HPO4)2 with different basal spacing. .This process was investigated by means of XRD, GC and liquid NMR. The results show that there are three steps in the cross-linking process. Firstly, the cross-liking agents are hy-drolyzed and condensed. Secondly, one type of polymerization state silicon is intercalated into layers in a-Zr(HPO4)2. H2O. Lastly, the intercalated compounds are calcined. During the calcination the groups on the layers react with silicon to form the zeolite like materials. .更多还原
