ABSTRACT
Isothermal vapour-liquid equilibrium data were measured for ethene + perfluoro-n-octane mixtures at five temperatures in the 293 353 K range, and pressures up to 8 MPa. Experimental P-x-y data were measured using an apparatus based on the static-analytic method. The experimental data were correlated with a model comprising the Peng-Robinson equation of state with either the classical mixing rule or the Wong-Sandler mixing rule coupled with the Non-Random Two-Liquid activity coefficient model. The model gave good representation of the experimental data.
