Vapor−Liquid Equilibria of Water + Methanol in the Presence of Mixed Salts

Vapor−Liquid Equilibria of Water + Methanol in the Presence of Mixed Salts

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 me...

Zusammenfassung: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.
