MEASUREMENT AND CORRELATION OF LIQUID-LIQUID EQUILIBRIA FOR TERNARY SYSTEMS OF WATER + RUBIDIUM CHLORIDE + PROPANOL

Liquid-liquid equilibria for ternary systems of water + rubidium chloride + 1-propanol and water + rubidium chloride + 2-propanol were measured at T = 298.15, 308.15, and 318.15 K. The experimental data were correlated using Othmer-Tobias and Bancroft correlations. The salting-out effect of 1-propanol in the two-liquid region was greater than that for 2-propanol, but the effect of temperature on the equilibrium was not significant.
