摘要
在Na_2O-HMDA-MO_(n/2)-SiO_2-H_2O体系中及160℃下合成了杂原子M-ZSM-48型分子筛(M=B、Ge),结构研究表明,杂原子进入了分子筛骨架,杂原子B以四配位方式存在。
M-ZSM-48 type molecular sieves were synthesized in the system of Na_2O-HMDA-MO_(n/2)-SiO_2-H_2O at 160℃ (M=B, Ge). The structures were in vestigated. It was shown that the hetero-atoms were introduced into the framework of the molecular sieves and that B exists in tetrahedral coordination.
