Micro-calorimetric measurements of excess molar enthalpies H E m are reported for {ethyl tert-butyl ether (ETBE, ethyl 1,1-dimethylethyl ether) + n-hexane, n-heptane, or n-octane}. These H E m values, together with those reported previously for tert-amyl methyl ether (TAME, 1,1-dimethylpropyl methyl

The isothermal and isobaric (vapour + liquid) equilibria (v.l.e.) for (N ,N -dimethylformamide + 2-propanol + 1-butanol) and the binary constituent mixtures were measured with an inclined ebulliometer. The experimental results are analyzed using the UNIQUAC equation with temperature-dependent binary
