以程序升温分解（ＴＰＤＥ）为主要研究手段，分析了β沸石中四乙基胺模板剂的热分解机理。结果表明，四乙基胺模板剂的热分解分四个阶段进行：第一阶段发生的是包藏于沸石孔道中的四乙基氢氧化胺（ＴＥＡＯＨ）的第一级Ｈｏｆｍａｎｎ降解反应；第二阶段是平衡骨架负电荷的四乙基胺离子（ＴＥＡ＋）的第一级Ｈｏｆｍａｎｎ降解反应以及第一阶段降解产物Ｅｔ３Ｎ再吸附后发生的连续不同级乙基取代胺的Ｈｏｆｍａｎｎ降解反应；第三阶段是前两阶段的降解产物再吸附后，再吸附产物的连续不同级乙基取代胺的Ｈｏｆｍａｎｎ降解反应；第四阶段是残留有机物的分解反应。
The pyrolysis mechanism of tetraethylammonium templating agent in β-zeolite was analyzed by temperature-programmed decomposition (TPDE) as the main research method. The results showed that the thermal decomposition of tetraethylammonium templating agent was carried out in four stages: the first stage was Hofmann degradation reaction of tetraethylammonium hydroxide (TEAOH) entrapped in zeolite pores; the second stage Is the first-order Hofmann degradation reaction of tetraethylamine ion (TEA +) that balances the negative charge of the framework, and the Hofmann degradation reaction of successive different ethyl-substituted amines that occurs after the first-stage degradation product Et3N is re-adsorbed; the third stage is the first After the two-stage degradation product is re-adsorbed, the Hofmann degradation reaction of consecutively different ethyl-substituted amines of the product is re-adsorbed. The fourth stage is the decomposition reaction of residual organic compounds.
