Saturated liquid densities and bubble point pressures of trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) + propane (R290) binary mixture were measured at temperatures from (253.141 to 293.284) K and mole fractions of R1234ze(E) from (0.1746 to 0.8803) using a compact single-sinker densimeter. The standard uncertainties were estimated to be less than 5 mK for temperature, 600 Pa for pressure, 0.003 for mole fraction, and 0.01% for density. The experimental saturated liquid densities were reproduced by the VDNS and our modified Rackett density equations, while the experimental bubble point pressures were represented with the Patel Teja (PT) equation of state. Good agreement between values of calculation and experiment were found for both saturated liquid densities and bubble point pressures. In addition, saturated vapor and liquid densities of azeotropy point at temperatures T = (258.150, 263.150, 273.150 and 283.150) K were determined.
