PvT properties, saturated densities, and critical parameters of R1132(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 at pressures up to 6.5 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 833 kg m−3. The critical temperature and density were also determined as Tc = 348.82 ± 0.01 K and ρc = 438 ± 3 kg m−3 on the basis of the meniscus disappearing level as well as the intensity of the critical opalescence.
