Isobaric vapor-liquid equilibria were measured for the six binary systems heptafluoropropyl methyl ether (HFE-347mcc) or 1,1,1,2,3,3-hexafluoro-3-propane (HFE-449mec-f) with 1-propanol, 2-butanone, or ethyl acetate at atmospheric pressure. The mixtures HFE-347mcc and HFE-449mee-f with I-propanol both formed a minimum boiling azeotrope. The mixtures HFE-449mec-f with 2-butanone and with ethyl acetate formed maximum boiling azeotropes, The experimental data were correlated by the Wilson and NRTL activity coefficient models. The Wilson and NRTL equations gave similar results.
