Liquid–liquid equilibrium of (water + 1-propanol + 1-pentanol) system at 298.15 and 323.15 K
Résumé
Liquid–liquid equilibrium data for the ternary system water + 1-propanol + 1-pentanol have been deter- mined experimentally at 298.15 and 323.15K using “static–analytic” apparatus involving ROLSITM samplers. The experimental data are correlated considering both NRTL and UNIQUAC activity coeffi- cient 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.
