In this paper, bubble point pressures and saturated liquid densities of {2,3,3,3-Tetrafluoroprop-1-ene (R1234yf) + propane (R290)} binary mixtures were measured using a compact single-sinker densimeter. Measurements were carried out over temperatures from (255.048 to 300.135) K and mole fractions of R1234yf at (0.113, 0.217, 0.322, 0.422, 0.533, 0.625). The experimental standard uncertainties were estimated to be less than 5 mK for the temperature, 2 kPa for the pressure, 0.003 for the mole fraction and 0.02% for the density. The experimental bubble point pressures were correlated by the Peng-Robinson equation of state, while the experimental saturated liquid densities were represented with the VDNS and our modified Rackett equations. In addition, saturated liquid densities of azeotropy point at temperatures T = (253.150, 263.150, 273.150, 283.150 and 293.150) K were determined based on our previous and present work.
