| 摘 要： | 用热分析法研究硅沸石ｓｉｌｉｃａｌｉｔｅ—１的主体／客体相互作用．被吸附的客体分子在程序升温下脱附．作为一种新概念，本文定义硅沸石骨架对客体分子亲和性ＡＴ为Ｔｄ与Ｔｂ之差值，其中Ｔｄ是微分失重（ＤＴＧ）曲线上客体分子的失重峰温，而Ｔｂ是其沸点．本文比较了２９种不同客体物质的亲和性次序．硅沸石Ｓｉｌｉｃａｌｉｔｅ—１对某些强极性的有机分子，如甲胺、乙胺及乙醛显示很高的亲和性．

| Abstract: | Thermal analysis have been used to investigate host/guest interaction of silicalite-1.The guest molecules were adsorbed onto the zeolite and desorbed from it by T. P. D.AT- a new concept on affinity of silicalite framework to the guest molecule has been defined as difference of Td and Tb,where Td is the temperature of weight loss peak at DTG curve and Tb the boiling temperature. The affinity order has been compared for 29 different guest molecules. Silicalite -1 shows strong affinity to some organic compounds with high polarity, such as methylamine, ethylamine and acetaldehyde. |
