• Vapour-liquid equilibrium (VLE)
• 2,3,3,3-Tetrafluoroprop-1-ene (R1234yf)
• Propane (R290)
• Azeotropic

The vapour-liquid phase equilibrium was measured using an apparatus based on the re-circulation method for the 2,3,3,3-tetrafluoroprop-1-ene + propane binary system. A total of 55 data points were obtained over the temperature range from 253.150 to 293.150 K. The experimental standard uncertainties were less than 5 mK for the temperature, 800 Pa for the pressure, and 0.005 for the mole fraction. The experimental data were correlated by the PR-VDW model and PR-HV-NRTL model. Both models can present the experimental data well and the PR-HV-NRTL model achieves a higher degree of precision. The relative deviations of pressure are within +/- 0.50% and the maximum absolute deviation of vapour mole fraction is 0.006 for the PR-HV-NRTL model. A positive azeotropic behaviour can be observed for the binary system.
