Abstract
In this article, new Gibbs free energy of mixing is derived when there are specific interactions between solvent-solute molecules and between solute-solute molecules in binary solutions. It is asssumed that a probability of specific interactions satisfies a binomial distribution. Using this Gibbs free energy of mixing, we investigate possible types of partial miscibilities and show that &#x3A9;-shaped temperature-composition phase diagrams can exist. We calculate &#x3A9;-shaped temperature-composition phase diagram of water-2-butanol system and compare that with result calculated by the method of Hino<sup>5</sup> et al. and the experimental data.
