双杂原子Ti-Fe-ZSM-5分子筛的合成与表征

Synthesis and Characterization of Zeolite Ti-Fe-ZSM-5 Containing Double Heteroatom

在无碱金属离子存在下，分别采用四丙基澳化铵（TPABr）和价格低廉的1，6-己二胺（1，6－HDA）和正丁胺（R—NH2）模板剂会成了双活性中心的Ti-Fe-ZSM-5分子筛．对沸石产物的物性及结构进行了表征，并利用苯酚羟基化反应及气相色谱分析方法证明其有双活性中心离子存在及协同作用的催化氧化性能．

The synthesis of zeolite Ti-Fe-ZSM-5 containing double heteroatom with silica solas Si sources, titanium sulfate and iron trichloride as the starting malerials and teterapropy-lammomium bromide, 1, 6-dihexamine and n-butylamine as the templates, respectively in theabsence of alkali metal ions was investigated in detail- Some physico-chemical properties and the structure of the product were characterized by using techniques of XRD, IR, SEM,Mossbauer, UV-Vis, ESR and TG-DTA. It is pr0ved that the double active centers exist inthe product, having a synergistic catalytic oxidative property by the method of GC analysis ina reaction of phenol hydroxylation.
