description

Abstract In this work, experimental liquid–liquid equilibria (LLE) data of the dipropyl ether + n-propanol + water and dipropyl ether + n-propanol + ethylene glycol systems are presented. The LLE of both systems have been measured at 283.15 and 323.15 K. The equilibrium data presented are correlated using NRTL and UNIQUAC equations. The reliability of these models is tested by comparison with experimental results. Moreover, the solvent capabilities of water and ethylene glycol were compared, concluding that ethylene glycol is the best solvent to extract n-propanol.
