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%. (C) 2017 Elsevier B.V. All rights reserved.
