In this study, a substitutive entrairier is found for the azeotropic process of water and isopropyl alcohol (IPA). Liquid-liquid equilibrium (LLE) data are measured for the ternary systems of water-IPA-benzene, water-IPA-cyclohexane, and water IPA-hexane at three different temperature values: 303, 313, and 323 K. The liquid-liquid equilibrium data are developed via an experimental setup equipped with equilibrium cell, magnetic stirrer, and gas chromatography units. Equilibrium compositions for the water-IPA system are found by using three different entrainers: benzene, cyclohexane, and hexane. Parameters calculated by nonrandom two-liquid (NRTL) and universal quasichemical (UNIQUAC) thermodynamic models are compared with the data obtained by experiments, and the comparison shows a good correlation between thermodynamic models and the experimental data.
