(Liquid plus liquid) equilibria of (tert-amyl ethyl ether plus ethanol plus water) at several temperatures

(Liquid + liquid) equilibrium data of (tert amyl ethyl ether + ethanol + water) were determined experimentally at T = (298.15, 308.15, and 318.15) K. The experimental results were correlated with the NRTL and UNIQUAC equations. The correlations were made at each temperature and for the three temperatures simultaneously. The best results were achieved with the NRTL equation, using alpha = 0.2 for the individual correlations at each temperature and alpha = 0.1 for the overall correlation. The experimental data were also compared with predicted values by the UNIFAC method. (C) 2001 Academic Press.
