From analyses of Langmuir-type isotherms and α<SUB>s</SUB>-plots for nitrogen adsorption, both the micropore volume and the external surface area have been determined for pillar interlayered montmorillonite (abbreviated as PILM) prepared by intercalating the polynuclear Al cation into the montmorillonite interlayer. The applicability of the Gurvitsch rule to microporous PILM samples was confirmed for adsorption of heptane, whereas the adsorbed amounts of polar adsorbates were dependent on dehydrated states of the alumina pillar. High density of benzene in the micropore independent of calcination temperature suggests some peculiar orientation of benzene in the adsorbed state due to its molecular shape. The interaction of a water molecule with the adsorption site is weak and dependent on the calcination temperature of PILM samples. On this basis, the inhibition of rehydration of the alumina pillar has been discussed.
