摘要
为满足研究沸石分子筛择形选择性的需要，对分子尺寸的估算进行了探讨。提出了分子最小横截面动力直径的概念，并介绍了估算实例。提供了石油化工和精细化工中常见化合物分子尺寸的估算结果，该估算结果对预测沸石分子筛择形吸附和催化性能有指导意义。
To meet the needs for study the shape selectivity of zeolite molecular sieves,an approach for estimation of molecular dimensions was developed.The concept of kinetic minimum cross sectional diameter has been proposed,and examples of calculation of kinetic minimum cross sectional diameters have been given.The molecular dimensions of important chemical compounds in petrochemical and fine chemical industry were provided.The calculated results are expected to be very instructive for predicting shape selective adsorption of zeolites and their catalytic behaviors.
