| 摘 要： | 在四甲基乙基二胺(TMEDA)-Na2O-SiO2-Al2O3-HO2系统中,水热反应产物的沸石相,随配料硅铝比提高,依次为Md(丝光沸石),TMEDA-Md,ZSM-35,ZSM-5,ZSM-39及一种我们称为CF-3的新沸石.从沸石的组成,性质,晶体结构与"模极分子"的构型等方面,讨论了TMEDA对诱导上述沸石的生成所起的电荷平衡与孔道充填的共同作用向笼的充填作用的转变.

| Abstract: | With the increase in silica:alumina ratio the hydrothermally crystd. zeolites in TMEDA (tetramethylethylenediamine)-Na2O-SiO2-Al2O3-H2O system were in the following order: Md(mordenite), TMEDA-Md, ZSM-35, ZSM-5, ZSM-39, and a novel zeolite CF-3. With respect to the composition, properties, and crystal structure of zeolites and the configuration of the template mol., the structure-directing effects of the template are discussed, which change from the combined effect of a cation balancing of the framework charge and channel occupation to the effect of cages occupation. |
