Differential heats of sorption have been determined calorimetrically for benzene, toluene, ethylbenzene, and p-xylene on silicate as a function of pore filling. In all cases abrupt changes in the state of the sorbed molecules are observed when the amount sorbed exceeds 1 molecule per 1/4 unit cell. While in the case of benzene, toluene, and ethylbenzene sorbate-sorbate interaction occurs only above 1 molecule per 1/4 unit cell, the sorbed p-xylene molecules interact with each other below this loading.
