| 摘 要： | 以不同分子筛(Nonasil, MCM-22或MCM-49)为晶种, 在水热条件下以六亚甲基亚胺(HMI)为模板剂, 对纯硅沸石Nonasil(HMI)的合成进行了研究. 并且对各种合成参数, 包括晶种类型、硅源、晶化温度和Na+浓度等对Nonasil(HMI)合成的影响进行了探讨. 发现在适量的Na+存在条件下, 晶种的引入大大缩短了晶化时间; 不同类型的晶种对晶化速度有不同程度的提高. 特别是用异类晶种(如MCM-22或MCM-49)能够合成高结晶度的Nonasil(HMI).

| Abstract: | By using different zeolites(Nonasil,MCM-22 or MCM-49)as the crystal seeds,the synthesis of Nonasil(HMI)porosil was studied under hydrothermal conditions in the presence of hexamethyleneimine(HMI)as the organic template.Various synthesis parameters,including the type of crystal seeds,silica source,temperatures and the concentrations of Na ,are investigated for the synthesis of nonasil(HMI).It was found that the addition of crystal seeds could considerably shorten the time of crystallization in the presence of appropriate amount of Na and that different kinds of crystal seeds could accelerate the crystal growth with different degrees.Particularlly,nonasil(HMI)with a high crystallinity level can be obtained with heterogeneous crystal seeds(i.e.MCM-22,MCM-49). |
