摘要：

Enthalpies and entropies of sorption of water on Linde 4-A and 5-A zelites have been evaluated from data provided by Union Carbide Corporation. The results above 5 molecules of water per unit cell of zeolite show the expected general behavior of water on the heterogeneous zeolite surface. Some interesting additional behavior is observed showing a temperature dependence of the heat of sorption at higher water contents than that required to cover the most energetic sorption sites. This is discussed in terms of the interactions possible in the zeolite cavities. © 1968.
