摘要/Abstract

摘要： 在合成一系列ZSM-5/11分子筛的基础上,用固体高分辨¹³C-NMR技术考察样品中模板剂TBA⁺的存在状态.讨论了TBA⁺在ZSM-5和ZSM-11孔道中的分布方式,并发现了TBA⁺的分解产物正丁胺的存在,从而说明了在SiO₂/Al₂O₃不十分高的体系中,TBA⁺和正丁胺是ZSM-5共生晶相的模板剂。

Abstract: On the basis of synthesising a series of ZSM-5/11 molecular sieves, the state of TBA⁺, the templating agent, within the framework of the samples were investigated by high-resolution solid-state ¹³C-NMR technique. The position and configuration of TBA⁺ within the channel of ZSM-5 and ZSM-11 molecular sieves were discussed and the product during the decomposition of TEA^-, n-butylamine, was discovered. Thereby, it was illustrated that TBA⁺ and n-butylamine both are the templating agents of ZSM-5 molecular sieve in the system with not very high SiO₂/Al₂O₃. From which ZSM-11 would be obtained.
