Abstract

An examination of the theoretical foundations of Trouton's and Hildebrand's rules gives an explanation of the greater generality of Hildebrand's rule. In a group of liquids obeying the principle of corresponding states those with the larger critical volumes Vc have smaller Hildebrand entropies of evaporation. But in many groups of non-polar liquids an increase in Vc is accompanied by a change in the form of the molecular interaction potential (with consequent departure from the principle of corresponding states) and this change can produce a compensating increase in Hildebrand's entropy.
