AbstractTetrachloroethylene and trichloro- fluoromethane exhibit hysteresis when adsorbed on anhydrous nickel sulfate. Analysis of the heats of adsorption and the entropies of the adsorbed substances suggests that condensation occurs during adsorption. This is corroborated by analysis of the data with the Kelvin equation. This analysis also indicates that the angle of contact between the condensed adsorbate and the adsorbent is not zero as is usually assumed, but is in fact, finite. The data suggest that layers of adsorbate of only two molecules' thickness can exhibit liquidlike properties. The shape of the isotherm suggests that the adsorbent consists of parallel plates separated by capillary spaces within which condensation occurs. The plates may move apart as adsorption progresses to accommodate large volumes of adsorbate between the plates.
