ZSM-5(参考文献1)和ZSM-11(参考文献2)是具有相似的二维交叉通道结构的富硅铝硅酸盐沸石。它们通常由Na+-四烷基铵(Na+-TAA)体系在高pH和约160°C的温度下合成(参考文献3-6)。我们在这里报告,我们认为是第一次使用系统的碱金属离子的合成沸石ZSM-5和ZSM-11。
ZSM-5 (ref.1) and ZSM-11 (ref. 2) are silica-rich aluminosilicate zeolites with similar two-dimensional intersecting channel structures. They are conventionally synthesised from Na+–tetraalkylammonium (Na+–TAA) systems at high pH and temperatures around 160°C (refs 3–6). We report here what we believe to be the first use of systems free of alkali metal ions in the synthesis of the zeolites ZSM-5 and ZSM-11.
