| 摘 要： | 分子筛的合成通常是采用含碱金属离子的强碱性体系,通过水热晶化法实现~1,2]的.得到的分子筛原粉不但必须通过铵离子交换和焙烧才能转变为氢型催化剂,而且在该体系中晶体的粒度也较小.Guth等人~3]首次报道了在非碱性介质F-离子存在下直接合成铵型ZSM-5的工作.除用四丙基溴化铵合成ZSM-5及其杂原子分子筛外~4],尚未见到在非碱性介质中合

| Abstract: | Zeolite P,ZSM-39,Theta-1 and ZSM-5 were synthesized by hydrothermal crystallization from non-alkaline media in the presence of fluoride ions by using various organic templates,and characterized by means of thermal analysis and scanning electron microscopy technique.Large single crystals of zeolite P,ZSM-39 and ZSM-5 were obtained.The influence of compositions of starting mixtures and temperature on the zeolite synthesis was investigated. |
