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。

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, GCand 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.
