ABSTRACT

In this study, a substitutive entrainer 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; 303k, 313k and 323k. The liquid liquid equilibrium data are developed via an experimental setup equipped with equilibrium cell, magnetic stirrer, and gas chromatography units. Equilibrium compositions for water-IPA system are found by using three different entrainers; benzene, cyclohexane and hexane. Parameters calculated by NRTL and 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.
