对低GWP制冷剂：3，3，3-三氟丙烯（HFO 1243 zf，CF 3CH CH 2）进行了PvT特性、饱和密度和临界参数的测量。75 PvT性能数据点沿着7等值线周围的临界点，得到的温度范围从328到430 K，在50和899公斤m-3之间的密度范围内，并在压力高达6.9 MPa的等容法。通过观察临界区弯月面的消失，得到了14个饱和密度。在此基础上，确定了临界参数Tc = 376.93 ± 0.01K，ρc = 414 ± 3 kg·m ~（-3）。目前的结果进行了比较，一个可用的状态方程。
Measurements of PvT properties, saturated densities, and critical parameters were carried out for a low-GWP refrigerant: 3,3,3-trifluoropropene (HFO1243zf, CF3CH═CH2). Seventy-five PvT property data points along seven isochores around the critical point were obtained in the temperature range from 328 to 430 K, in the density range between 50 and 899 kg m–3, and at pressures up to 6.9 MPa by the isochoric method. Fourteen saturated densities were obtained by the observation of meniscus disappearance in the critical region. On the basis of these measurements, the critical parameters of Tc = 376.93 ± 0.01 K and ρc = 414 ± 3 kg m–3 were determined. The present results are compared to an available equation of state.
