摘要：

Isothermal vapor liquid equilibrium data for the binary system of 2,3,3,3-tetrafluoroprop-1-ene (HFO-1234y0 +1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea) were measured at 10 K intervals from 283.15K to 323.15 K over the whole composition range. The uncertainties of the experimental data are estimated at +/- 5 mK, +/- 3.5 kPa, and +/- 0.003 for the temperature, pressure, and the equilibrium liquid and vapor mole fractions, respectively. The experimental data were correlated with the Peng Robinson equation of state using the van der Waals mixing rule, and the binary interaction parameter was optimized to fit the experimental data. The comparison between the experimental data and the correlated results shows a good agreement. (C)2014 Elsevier B.V. All rights reserved.
