2,3,3,3-tetrafluoroprop-1-ene (HFO-1234yf) is considered as the promising alternative low-GWP refrigerant to replace HFC-134a. In this study, the gaseous pvT properties of HFO-1234yf were measured at temperatures from 252 K to 345 K and pressures up to 1.91 MPa using a single-sinker densimeter. The density range is from 3.732 kg/m3 to 112.152 kg/m3. The standard uncertainties of the experimental data are estimated as 6 mK and 0.7 kPa for the temperature and pressure, respectively. The relative uncertainty in density is (0.014 to 0.034) % in this study. The average absolute deviation and relative deviation of density from reported equation of state are 0.023 kg/m3 and 0.156 %, respectively. A virial equation of state was developed for HFO-1234yf. The calculated results show good agreement with the experimental data.
