摘要：

Isothermal vapor liquid equilibrium (VI,E) data are presented for the system hexafluoropropylene (R1216) propylene (R1270) Measurements were performed for six isotherms ranging from (263 17 to 353 14) K. at pressures from (0 224 to 4) 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 and the samplers were developed in the CEP/TEP laboratory The uncertainties in the measurements are within +/- 0 02 K, +/- 0 0005 MPa, and less than +/- 4 0 % for temperature, pressure, and mole fractions, respectively The I till set of isothermal VLE data is correlated with the Peng-Robinson equation of state (PR EoS), incorporating the original Soave alpha function, with the Wong-Sandler mixing rule utilizing the nonrandom two-liquid (NRTL) activity coefficient model
