Isobaric vapor-liquid equilibria for bis(2,2,2-trifluoroethyl)ether + alcohols, ketones, or esters systems were measured at 101.3 kPa. The alcohols used are methanol, ethanol, 1-propanol, and 2-propanol. As the ketones 2-butanone was used, and used as esters ethyl acetate. The measurements were made in an equilibrium still [T. Hiaki, K. Kawai, Fluid Phase Equilibr 158-160 (1999) 979] with circulation of both the vapor and Liquid phase. The four binary isobaric systems of the CF3CH2OCH2CF3 and the alcohols form a minimum boiling azeotrope. The azeotropic points are found at x(1)(az) = 0.555 mole fraction and T (az) = 326.28 K for CF3CH2OCH2CF3 (1) + methanol (2), x(1)(az) = 0.716 mole fraction and T (az) = 331.90 K for CF3CH2OCH2CF3 (1)+ ethanol (2), x(1)(az) = 0.890 mole fraction and T(az) = 336.22 K for CF3CH2OCH2CF3 (1) + 1-propanol (2), and x(1) (az) = 0.777 mole fraction and T (az) = 334.16 K for CF3CH2OCH2CF3 (1) + 2-propanol (2). The two binary systems of CF3CH2OCH2CF3 (1)+ 2-butanone (2) and CF3CH2OCH2CF3 (1) + ethyl acetate (2) are both non-azeotropic. The experimental data of the binary systems investigated were correlated with activity coefficient equations. The nonrandom two-liquid (NRTL) equation yielded a good correlation of activity coefficients for four systems of CF3CH2OCH2CF3 with alcohols. Two systems of CF3CH2OCH2CF3(1) + 2-butanone(2) and CF(3)CH(2)OCH(2)CF3(1) + ethyl acetate (2) were best correlated with the three-suffix Margules equation.
