Isobaric vapor-liquid-liquid-solid equilibria for the ternary system water + sodium chloride + 1-propanol have been determined at 101.3 kPa by means of a modified recirculating still. The addition of sodium chloride to the solvent mixture results in the appearance of different equilibrium regions. A detailed quantitative analysis of the evolution with temperature of the phase diagram has been carried out. The experimental data obtained in this way have been compared, on the one hand, with previously published data containing important inconsistencies and, on the other hand, with data calculated by the extended UNIQUAC model.
