Because of attraction between water molecule and carbonium ion, the severe contract in system volume brings about activation volume effect (the most negative A〓 observed in this work is 407cm〓mol〓), which produces subtle relationship between reaction kinetics and pressure in a certain operating region.

反应过渡产物正碳离子及水合正碳离子与近临界状态水分子之间强烈相互吸引导致反应活化体积出现极负值现象（本实验所测极值为-407cm〓·mol〓，这使得水解动力学参数对反应压力存在敏感依赖关系。

X6 3?,large specific surface area and adsorbent capacity However,most molecules and hydrated ions can not enter the aperture pass because of their size over the aperture diameter of palygorslote except less simple ones Furthermore,Palygorskite adsorbs water molecule choosingly In most cases the absorbing of palygorskite is by its outside surface that works in the form of colloid and ion exchange other than i...

但是由于凹凸棒石孔道直径小于大多数分子及水合离子的直径，除少数简单分子和离子外，多数分子和离子都不能进入凹凸棒石孔道，而且凹凸棒石选择性吸附水分子，因而在多数情况下，凹凸棒石对吸附质的吸附不是内表面吸附，而是外表面吸附。并且外表面吸附是胶体和离子交换吸附。本文阐述了凹凸棒石的孔道直径、吸附选择性、体系pH 值及凹凸棒石和蒙脱石胶体颗粒的互相作用对凹凸棒石吸附性能应用的制约。
