The Freezing of Water and Benzene in Porous Vycor Glass

Abstract: Freezing has been detected in the adsorbed water and benzene of porous Vycor glass a t temperatures below that a t which the bulk phases freeze. The evidence presented by equilibrium pressure measurements and dimensional changes of the systems is considered in terms of theories of capillary condensation and freezing in cements and soil. Although not all the results can be esplained, it is concluded that the freezing process is a gradual one for both adsorbate-adsorbent systems. The evidence further suggests th… Show more

“…The sharp change of slope of the vapor pressure isosteres does not prove that the transition is sharp as has been pointed out (7). T h e existence of a freezing range is to be expected according to the n~olecular picture of phase changes in adsorbed layers.…”

“…But even so, the number of experimental results not explicable by the theory is growing and it seems desirable to examine its applicability under various conditions. One means of testing the theory has been shown to be the study of phase transitions of adsorbates (6,7). The present work is a continuation of that investigation.…”

“…Great care was taken to ensure that deposition did not occur on the wire holding the sample to the spiral, or on the outer surface of the sample; after each temperature change was effected, the sample was pumped slightly and was then allowed to return to equilibrium. A "cooling-warming" isostere was also measured, in the same nlanner as other workers (5)(6)(7)(8). This experiment served as a useful comparison especially since the samples used in this work had different surface areas and porosities to the samples of other workers.…”

“…Isosteres As stated previously, this experiment probably leaves a saturated porous system in an undefined state, but because of its practical importance (it is the kind of treatment a material will receive in nature) and because many measurements of this type have been made previously (2,(5)(6)(7)(8) and have been correlated with calorimetric measurements (9, 81, it was deemed necessary to perform this experiment to provide comparison with previous results and to compare present results with those of experiments of Sections (1-4). It is thought that a satisfactory explanation can now be provided for the "cooling-warming" isosteres.…”
