Pvt Properties Of 2,3,3,3-Tetrafluoroprop-1-Ene (Hfo-1234yf) In The Gaseous Phase

2,3,3,3-Tetrafluoroprop-1-ene (HFO-1234yf) is considered as the promising alternative low-global warming potential refrigerant to replace HFC-134a. In this study, the gaseous pvT properties of HFO-1234yf were measured at temperatures from 252 to 345 K and pressures up to 1.91 MPa using a single-sinker densimeter. The density range is from 3.732 to 112.152 kg/m(3). 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 0.014-0.034% in this study. The average absolute deviation and relative deviation of density from reported equations of state are 0.024 kg/m(3) and 0.157%, respectively. A virial equation of state was developed for HFO-1234yf. The calculated results show good agreement with the experimental data.
