Vapor-Liquid equilibria of water + methanol, in the presence of binary salts of sodium chloride, potassium chloride, and sodium bromide, were studied at 298.15 K. The single salt-mixed solvent systems were also reported. A modified Othmer still was employed. The estimated accuracy of the pressure measurements was 0.12 kPa. The experimental results were compared with the predictions of the method of Lee et al.
