Thermodynamic Model And Sum Rules For Three-Phase Coexistence Near Thetricritical Point In A Liquid Mixture, Miron Kaufman, K. K. Bardhan, Robert B. Griffiths
Miron Kaufman
Two sum rules for order-parameter susceptibilities are derived for the classical theory of the three-phase region near a tricritical point in ordinary liquid mixtures. The classical theory can also be fitted in a quantitative way to the composition data of Lang and Widom near the tricritical point in the mixture ethanol+ benzene+ water + ammonium sulfate.
