Isothermal vapor-liquid equilibrium data are presented for the system hexafluoroethane (R116) + propane. Measurements were performed for six isotherms (three isotherms below and three above the critical temperature of R116) ranging from (263.3 to 323.19) K, with pressure ranging from (0.344 to 3.851) MPa. The measurements were undertaken using a static-analytic type apparatus, with sampling of the equilibrium phases via pneumatic capillary samplers (Rolsi, Armine s patent). The apparatus as well as the samplers were developed in the CEP/TEP laboratory. The uncertainties in the measurements were within ( 0.01 K, ( 0.0003 MPa, and less than 2.0 % for temperatures, pressures, and mole fractions, respectively. The full set of isothermal vapor-liquid equilibrium data was correlated with the Peng-Robinson equation of state, incorporating the Mathias-Copeman alpha function, with the Wong-Sandler mixing rule utilizing the NRTL activity coefficient model.
