The vapour-liquid equilibrium data for the C2F4-C3F6-s-C4F8 system are presented. Each binary system was evaluated at three isotherms. The experimental data will be correlated to the Peng-Robinson equation of state, incorporating the Mathias-Copeman alpha function, with the Wong-Sandler mixing rule utilising the NRTL activity coefficient model.
