(Liquid-liquid) equilibrium (LLE) data for the ternary systems of {water+carboxylic acid (formic, acetic, propionic or butyric acid)+ dimethyl maleate} were measured at T=298.2 K and atmospheric pressure. Selectivity values for solvent separation efficiency were derived from the tie-line data. A comparison of the extracting capabilities of the solvent 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 phase diagrams for the ternary mixtures including both the experimental and calculated tie-lines were presented.
