ABSTRACT
Liquid-liquid equilibrium data for the ternary system water + 1-propanol + 1-pentanol have been determined experimentally at 298.15 and 323.15 K using static-analytic apparatus involving ROLSI samplers. The experimental data are correlated considering both NRTL and UNIQUAC activity coefficient models. The results obtained show the ability of both models for the determination of liquid liquid equilibrium data of the studied system. The reliability of the experimental tie-line data is determined through the Othmer-Tobias and Bachman equations.
