Isobaric Vapor–Liquid Equilibria at 50.0, 101.3, and 200.0 kPa. Density and Speed of Sound at 101.3 kPa and 298.15 K of Binary Mixtures HFE-7100 + 2-Propanol Muñoz Rujas, Natalia Rubio Pérez, Gabriel Montero García, Eduardo Aguilar Romero, Fernando Ingeniería Química Termodinámica Chemical engineering Thermodynamics Isobaric vapor–liquid equilibria (VLE) at 50.0, 101.3, and 200.0 kPa, have been measured for the binary system methyl nonafluorobutyl ether (x1) HFE-7100 + (1 – x1) 2-propanol. Thermodynamic consistency was checked by applying the Wisniak point to point and area tests, as well as the Fredenslund point to the point test. Vapor–liquid equilibrium data have been correlated by means of Wilson, NRTL, and UNIQUAC equations. The three binary systems show positive azeotropes at every measured pressure. Densities and speeds of sound were determined experimentally at 101.3 kPa and at 298.15 K. Excess volumes, isentropic compressibilities, and deviations in isentropic compressibility were calculated from experimental data. The Redlich–Kister polynomial was used to correlate excess properties upon mixing, showing a good agreement between experimental and calculated values.
