Résumé

The fluorinated propene isomer R1243zf (3,3,3-trifluoroprop-1-ene, CF3CF=CH2, CAS number 677-21-4) is a potential alternative refrigerant due to its short atmospheric lifetime and therefore correspondingly low GWP. It has low acute toxicity; however, it is flammable, and thus is being considered primarily as a component in blends. Data existing in the literature include vapor pressure, critical temperature, and critical pressure from two groups of authors from three different laboratories. In this paper, 302 subcooled liquid density data and 101 vapor phase PvT data are presented. The subcooled liquid density data are measured for eight isotherms, evenly separated approximately from 283 K to 353 K, for pressures from close to saturation to 35 MPa and the vapor phase PvT data are measured for six isochores for temperatures approximately from 278 K to 368 K and for pressures approximately from 260 kPa to 912 kPa. In addition, a saturated liquid density correlation, a Tait correlation for the subcooled liquid density data, and a Martin-Hou Equation of State for the vapor phase PvT data are presented.
