摘要: 在碱性介质中,以甲基三乙基溴化铵为模板剂,采用水热晶化法合成了M-ZSM-12型(M=B,Ga,Ge)分子筛,考察了影响合成的因素。通过x射线衍射、扫描电镜、IR、XPS、29Si高分辨固体核磁共振谱和TG-DTA等方法证明了M对ZSM-12型分子筛骨架的同晶取代。

Abstract: M-ZSM-12(M=B, Ga, Ge)Zeolites were synthesized from a mixture containing triethylmethylammoniumbromide as template agent in a basic medium. The factors affecting the synthesis were investigated. M-ZSM-12 were charaterized by means of XRD, SEM, IR, XPS, 29Si MAS NMR, and DTA, which proved that M was situated in the zeolites framework.
