Thermodynamic properties measurement of HFO1132(E).

Number: 1024

Author(s) : SAKODA N., HIGASHI Y.

Summary

PvT properties, saturated densities, and critical parameters of HFO1132(E) were measured with two kinds of experimental apparatus. Along eight isochores between 65 and 832 kg m-3, PvT property measurements were carried out in the temperature range from 310 to 400 K and pressures up to 6.4 MPa by the isochoric method. The saturated-vapor and saturated-liquid densities were determined by the visual observation of meniscus disappearance and by the break point of the PvT property isochores in the temperature range from 304 K to the critical temperature and in the density range from 65 to 840 kg m-3. The critical temperature and density were also determined as Tc = 348.82 ± 0.01 K and c = 438 ± 3 kg m-3 on the basis of the meniscus disappearing level as well as the intensity of the critical opalescence.
