Measurements are reported on phase equilibria of the four mixtures propan-1-ol + water + sodium chloride, propan-1-ol + water + potassium chloride, propan-2-ol + water + lithium chloride, and propan-2-ol + water + lithium bromide at atmospheric pressure. The phase behavior of these mixtures exhibits three-phase equilibria, two liquids and one vapor, different from the previous reports that these only exhibit two phases. The phase diagrams for these mixtures are discussed.
