ABSTRACT
(Liquid liquid) equilibrium (LLE) data for the ternary systems of water + 1-propanol + solvent (n-amyl acetate, cyclohexanol, and cyclohexyl acetate) were measured at T = 298.2K and atmospheric pressure. Selectivity values for solvent separation efficiency were derived from the tieline data. A comparison of the extracting capabilities of the solvents was made with respect to distribution coefficients, separation factors, and solvent-free selectivity bases. The reliability of the data was ascertained from Othmer Tobias plots. The experimental data were correlated using the UNIQUAC and NRTL (a = 0.2) equations, and the binary interaction parameters were reported. The data were satisfactorily predicted by the UNIFAC group contribution method. The phase diagrams for the ternary mixtures including both the experimental and calculated tie-lines were presented.
