Values of gaseous p.rho.Tx were measured with a compact single-sinker densimeter for {2,3,3,3- tetrafluoroprop-1-ene (HFO1234yf) + propane (HC290)} mixtures. A total of 168 data points was obtained at temperatures from (265.460 to 300.268) K, pressure up to 0.70252 MPa, and mole fractions of HFO1234yf at (0.0906, 0.2546, 0.5830, 0.8116, and 1.0000). For the densimeter, values of the experimental standard uncertainty were less than 5 mK for the temperature, 200 Pa for the pressure, and 0.0003 for the mole fraction. When all the experimental standard uncertainties are considered, the relative uncertainty in density was estimated to be less than 0.13%. The experimental results were correlated using a truncated virial equation of state (EOS) and the Patel-Teja (PT) EOS. The virial model gives the best description of the experimental pqTx values with average absolute relative deviations of 0.080% in pressure and 0.085% in density.
