Measurements of Vapor Pressure and Saturated Liquid Density for HFO-1234ze(E) and HFO-1234ze(Z)

Vapor pressure and saturated liquid density for HFO-1234ze(E) and HFO-1234ze(Z) were measured in the temperature range from 300 to 400 K by using the extraction method. Experimental uncertainties are estimated to be 0.028 K for temperature, 0.4 kPa for pressure, and 0.9 kg.m(-3) for density. Vapor pressures were obtained in the pressure range from 526 to 3462 kPa for HFO-1234ze(E) and from 185 to 2309 kPa for HFO-1234ze(Z). Saturated liquid densities were obtained in the density range from 670 to 1158 kg.m(-3) for HFO-1234ze(E) and from 843 to 1220 kg.m(-3) for HFO-1234ze(Z). These data are compared with the existing equations of state.
