ABSTRACT
(Liquid + liquid) equilibrium data for the ternary system (dibutyl ether + methanol + water) were experimentally determined T = (298.15, 308.15, and 318.15) K. The experimental results were correlated by means of the NRTL and UNIQUAC equations, the best results being achieved with the UNIQUAC equation, both for the individual correlations at each temperature and for the overall correlation considering all the three experimental data sets. The experimental tie-lines were also compared to the values predicted by the UNIFAC method.
