ZSM-35分子筛合成及影响因素研究

Synthesis of ZSM-35 zeolite and its influencing factors

在氢氧化钠和氢氧化钾溶液中，以环己胺和硅溶胶为原料，通过K’与Na’对丝光沸石生成的抑制，成功合成了纯度很高的ZSM-35分子筛相，并利用X-光衍射分析仪对不同条件下形成的样品XRD光谱图，对影响ZSM-35分子筛生成的外界因素进行了分析，结果显示：ZSM-35分子筛形成的最佳碱度是3．3～3．5，n（SiO2）：，n（A1202）=20，晶化时间为40h时，ZSM-35分子筛的特征衍射峰强度很高，可以合成高纯度度晶化的ZSM-35分子筛样品，为ZSM-35分子筛的开发利用提供新的思路。

Using cyclohexylamine and silica as raw materials in sodium hydroxide and potassium hy- droxide solution. K＋ and Na＋ can inhibit the mordenite generated. We successfully synthesized high purity zeolite ZSM-35 phase, and using X-ray diffraction analyzer XRD spectra analyzed the samples formed under different conditions, and investigated the external influencing factors. The analysis re- sults showed that：the best alkalinity formation of zeolite ZSM-35 is 3.3~3.5 ,n（SiO2 ）/n（A1203 ）= 20,the crystallization time is 40 h, the characteristic diffraction peak intensity of ZSM 35 zeolites is high, the high purity degree of crystallization of ZSM-35 zeolite samples can be synthesized,it provides the new ideas to zeolite ZSM-35 exploitation and usage.
