ABSTRACT

Experimental vapour-liquid equilibrium data are reported for the binary systems of perfluorooctane + either oxygen, nitrogen or methane. Isothermal measurements were performed within the temperature range of (293.21 to 353.23) K, and at pressures up to 21 MPa, using two apparatuses; one based on the static-analytic method and the other on the static-synthetic method. The experimental data were correlated using the perturbed-chain statistical associating fluid theory equation of state. The model provides a satisfactory representation of the experimental data within the measured temperature range.
