Heat of Vaporization and Other Properties of Dioxane, Water and Their Mixtures

velopment of a theory of the salting-out or saltingin phenomenon. Such an approach appears adequate for the non-polar solute benzene which is considered. Their method is of such generality that it promises to provide the necessary foundation from which a more complete theory including the effects (1) and (3) discussed above may be formulated. The treatment of McDevit and Long is somewhat reminiscent of the much earlier concept of Tammann14 of an “internal pressure” (Binnendruck). He defined the increase in internal pressure of a salt solution in terms of the external pressure that would have to be applied to pure water in order to make properties such as the temperature of maximum density the same as for the salt solutions. Attempts were made by Euler15 and Geff-
