| 摘 要： | 在Na_2O-1.6-C_6H_(14)N_2-SiO_2-TiO_2-H_2O体系中首次用快速动态法和静态法合成了TiZSM-48型分子筛,考察了两种合成方法的晶化动力学。利用XRD、IR、XPS、SEM、DRS、TG-DTA等测试手段对TiZSM-48型分子筛进行了表征,结果表明,Ti进入了分子筛骨架,动态法合成比静态法合成快得多,且样品的晶粒较小。热分析表明,两种方法合成的样品热稳定性均较好。

| Abstract: | The TiZSM-48 zeolite was synthesized under a dynamic condition by using 1,6-hexamethy-lene-diamine as the template. The crystallizing rate of the dynamic state method was compared with that of the statical state method. The results show that the crystallizing rate of the former is much faster than that of the latter. The structure and properties of TiZSM-48 were investigated by IR, XRD, EPMA, XPS, DRS, ect.. The results confirm that Ti4+ occupies T site of the framework of the zeolite and are well distributed. |
