In this work, experimental liquid鈥搇iquid equilibrium data for four ternary systems containing {water + acrylic acid + solvent} were determined at 298.15 K and atmospheric pressure. The experimental data were also compared with the values correlated by the nonrandom two-liquid (NRTL) and universal quasichemical (UNIQUAC) models. Good quantitative agreement was obtained with these models. In general, the average deviation from the NRTL model is slightly greater than those from the UNIQUAC model. The reliability of the experimental tie-line data was confirmed by using the Othmer鈥揟obias correlation.
