Abstract Micro-calorimetric measurements of excess molar enthalpies H-m(E) are reported for {ethyl tert-butyl ether (ETBE, ethyl 1,1-dimethylethyl ether) + n-hexane, n-heptane, or n-octane}. These H-m(E) values, together with those reported previously for tert-amyl methyl ether (TAME, 1,1-dimethylpropyl methyl ether) + n-alkane, all measured at T = 298.15 K, were used to predict (vapour + liquid) equilibria v.l.e. for (ETBE, or TAME + n-alkane) and (ETBE, or TAME + n-alkanes) at isobaric/isothermal conditions. The predictions were made using the excess Gibbs free energy model of Liebermann and Fried. The predicted v.l.e. values are in good agreement with the literature values, and are comparable to reported correlation results obtained from four activity coefficient models (Wohl, Wilson, NRTL, and UNIQUAC).
