ABSTRACT
The liquid liquid equilibria for binary systems of tert-amyl ethyl ether (TAEE) +water, isopropyl tert-butyl ether (IPTBE) +water and di-secbutyl ether (DSBE) +water are analytically determined in the temperature range 278.65 358 K. Additionally, tie-lines for six ternary systems of TAEE, IPTBE and DSBE with methanol and water or with ethanol and water are also measured at 298.15 K. All the measured binary and ternary data were correlated with the NRTL and UNIQUAC model. The reliability of the experimental tie-line data for ternary systems was ascertained by using the Othmer Tobias correlation.
