本研究介绍了低GWP型制冷剂反式-1,1,1,3-四氟丁-2-烯（HFO-1354mzy(E)）的性能和关键参数的实验测量。该物质的样品纯度为99%。采用带光学单元的金属波纹管体积计对HFO-1354mzy(E)的半月板进行了性能测量和视觉观察。通过观察临界乳光来确定临界温度。确定了临界压力和临界密度作为临界温度下等温性能数据的拐点。为了更精确地澄清临界点附近的热力学表面，在超临界区域的三条等温线上进行了额外的性质测量。估计温度、压力和密度测量的扩展不确定度（）分别小于3 mK、1.2 kPa和0.32。关键参数的扩展不确定度分别小于13 mK、1.4 kPa和2.3。这些值是首次报道的HFO-1354mzy(E)的值，对于在不久的将来发展其状态方程是必要的。
This study presents the experimental measurement of theproperties and critical parameters of a low GWP type refrigerant,trans-1,1,1,3-Tetrafluorobut-2-ene (HFO-1354mzy(E)). The sample purity of the substance was 99 area %.property measurements and visual observations of the meniscus of HFO-1354mzy(E) were carried out using a metal-bellows volumometer with an optical cell. The critical temperature was determined by observation of the critical opalescence. The critical pressure and critical density were determined as the inflection point of the isothermalproperty data at the critical temperature. For more precise clarification of the thermodynamic surface in the vicinity of the critical point, additionalproperty measurements were carried out on three isotherms in the supercritical region. The expanded uncertainties () in the temperature, pressure, and density measurements were estimated to be less than 3 mK, 1.2 kPa, and 0.32, respectively. The expanded uncertainties of the critical parameters were estimated to be less than 13 mK, 1.4 kPa, and 2.3, respectively. These values are the first reported for HFO-1354mzy(E) and are necessary for the development of its equation of state in the near future.
