Measurements of vapor pressure and gaseous pvT property for trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E))

Abstract

The saturated vapor pressures and gaseous pvT properties for trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)) were measured using a Burnett apparatus. For vapor pressure, 15 data points were obtained in the temperature range from (303–373) K and pressure range from (578–3027) kPa. The experimental data was correlated by a Wagner type equation with the average absolute deviation of 0.003%. For gaseous pvT property, 101 data points were obtained in the temperature range from (313–373) K, pressure range from (117–2831) kPa and density range from (0.05–1.6) mol·dm−3. The second and third virial coefficients along 13 isotherms were obtained. The density data were correlated by a three-term truncated virial equation of state with a relative standard deviation of 0.06%.
