Bubble pressure data for the system of hexafluoroethane and n-octane were measured at four temperatures in the range of (292.9 to 323.4) K, and at pressures of up to 5.6 MPa. These isothermal P-x data were measured using a variable-volume static-synthetic apparatus. The Peng-Robinson Equation of State, modified with the Mathias-Copeman alpha function, coupled to the Wong-Sandler mixing rule, was used to model the experimental data. The Non-Random TwoLiquid activity coefficient model was used to model the excess Gibbs energy term within the WongSandler mixing rule. The temperature dependency of the thermodynamic model parameters was investigated at the temperatures for which data were measured. The binary system was categorised according to the van Konynenburg and Scott classification system.
