Summary

Thermodynamic properties of HCFO-1224yd(CF3CF=CHCl), including critical parameters, vapor-liquid coexistence curve, vapor pressure and PVT properties, were determined experimentally. The measurements of vapor-liquid coexistence curve in the critical region were made through visual observation of the disappearance of meniscus at the vapor-liquid interface within an optical cell. The vapor pressure and the PVT properties were made using the constant-volume method. The saturated liquid densities were obtained by the method using pyrex glass floats. The critical density was determined as 530±5kg/m3. The critical temperature was determined 429.18±0.05K as the saturation temperature corresponding to the critical density. The critical pressure was determined by extrapolation of the vapor pressure measurements to the critical temperature as 3.380±0.005MPa.
