Summary
-
1.
The adsorption space in synthetic mordenite are the large channels, formed by the twelve-membered oxygen windows, and the blind small channels or niches, belonging to pairs of eight-membered oxygen windows, that branch from them.
-
2.
The volumes of the channels and niches, calculated from the x-ray structure data, are found to be in entirely satisfactory agreement with the limiting adsorption volumes of mordenites in the sodium and hydrogen forms as regards the adsorption of nitrogen, argon, water and benzene.
