ABSTRACT
In this work, experimental liquid liquid equilibria data of the systems 4-methyl-2-pentanone + 1- propanol + water and 4-methyl-2-pentanone + 2-propanol + water are presented. The liquid liquid equilibria of both systems have been measured at 283.2 and 323.2 K. The NRTL and UNIQUAC models were successfully applied to fit the data for both ternary systems. The binodal lines were compared to the values predicted by the UNIFAC-LLE and UNIFAC models. Moreover, the solvent capability of 4- methyl-2-pentanone was checked in order to separate the azeotropic mixtures formed by propanol s and water.
