ZSM-12沸石的合成
摘要:
在水热体系中以甲基三乙基碘化铵为结构导向剂合成了SiO2/Al2O3=32.2~∞的ZSM-12分子筛,XRD和IR证明它们具有MTW拓扑结构;并以SEM和DTA表征晶体形貌和热稳定性,考察了催化性能。

SYNTHESIS OF ZEOLITE ZSM-12
Abstract:
Zeolite ZSM-12 has been synthesized by the hydrothermal method from the mixture of Na2O-Al2O3-SiO2-methyhriethylammonium iodide-H2O at 433K in a static autoclave.The products have SiO2/Al2O3≥32.2. The thermal stability and catalytic activity of ZSM-12 in the alkylation of benzene-ethylene have been examined.
