Abstract

Liquid–liquid equilibria of three ternary systems {glycerol + acetone + water}, {glycerol + 1, 4-dioxane + water}, and {glycerol + acetonitrile + water} were measured at temperatures of 288.15, 298.15, and 308.15 K. The results of the first two systems were satisfactorily correlated with the UNIQUAC equation with average deviations of 0.74 and 0.81%, respectively. Those of the last system were well correlated with a deviation of 2.49%. Glycerol was verified as a suitable solvent to remove water from acetone + water and acetonitrile + water solutions, through investigation of the distribution coefficients and selectivity for water, combining vapor-liquid equilibria of the systems {acetone + water} and {acetonitrile + water} at atmospheric pressure.
