Estimation of the Interchange Energy for Binary Systems from Mutual Solubility Data

Article metrics

Abstract

IF the theory of strictly regular solutions developed by Guggenheim1 is applied to ordinary binary systems and compared with experiment in order to evaluate the interchange energy the results are not good, since very few systems satisfy all the conditions for forming regular mixtures, in which the molecules are assumed to be sufficiently alike in size and shape to be interchangeable on a lattice or quasi-lattice. A few examples have been shown for this comparison. It is desirable that more comparisons with many experimental results are made in order to verify the validity of the theory and to extend their application to the field of the chemical engineering design.
