ABSTRACT
Measurements of vapor-liquid equilibrium data in binary systems methyl nonafluorobutyl ether + solvent (acetone, cyclopentyl methyl ether, ethyl acetate, n-heptane, methanol, and toluene) were carried out at constant temperature (328.15 or 318.15 K) by means of a vaporliquid equilibrium circulation still. In the most cases, the acquired data satisfied thermodynamic consistency tests. The obtained vapor-liquid equilibrium data were (successfully) correlated by two principally different thermodynamic models: the NRTL equation for the excess Gibbs energy, and the PC-SAFT equation of state. The latter model was tested also for its predictive capabilities and was found not to be suitable for reliable predictions in the studied binary systems, although it may correctly predict the azeotropic behavior of some systems.
