摘要： 红外光谱法研究分子筛的骨架振动得出了在X、Y等沸石分子筛骨架上振动频率与四面体中铝含量的线性关系[1]。但未见到有关ZSM-5型的报道.本文用红外光谱法系壳探讨了硅铝比和ZSM-5及ZSM-11的骨架振动频率之间的线性关系,并将由IR得到的SiO2/Al2O3比与化学分析值进行了比较。

Abstract: The frameworks on ZSM-5 and ZSM-11 zeolites with different ratios of Si/Al were studied by means of IRmethod. The internal tetrahedral asymmetrical stretch vibration frequencies of ZSM-5 and ZSM-ll increased linearly with the increasing of SiO2/Al2O3 ratios. SiO2/Al2O3 ratios obtained by IRmethod rather agreed with those obtained by chemical analytic method.
