Abstract

Due to the rising cost of energy, new separation processes based on extraction are becoming more attractive than before. Thus, the need for calculating and predicting liquid-liquid equilibria(LLE) compositions has very much increased. The purpose of this study is to determine the binodal curves, tie line, plait point, distribution and selectivity for the ternary systems of 2-propanol-water with methyl ethyl ketone, methyl isobutyl ketone, ethylacetate, toluene and o-xylene as solvents at $25^{\circ}C$. And those tie line data were used to examine thermodynamic consistency. The experimental tie line data were correlated with NRTL and UNIQUAC models.
