In this paper, 182 pvTz data (28 data in the two-phase region and 154 data in the superheated vapor region) of mixtures containing difluoromethane (R32) and trans-1,3,3,3-tetrafluoroprop-1-ene (R1234ze(E)) are reported. The measurements were carried out along 10 isochores (0.013173, 0.039422, 0.043115, 0.046522, 0.062966, 0.068225, 0.068959, 0.110447, 0.115156, and 0.121732 m3·kg–1) in the temperature range from 263 to 373 K for 10 R32 mole fractions (0.1677, 0.2360, 0.2551, 0.4634, 0.5374, 0.6715, 0.7383, 0.7544, 0.9532, and 0.9533). The flash method with three equations of state (EoSs) was used to assess the vapor–liquid equilibrium of the binary mixture under analysis. The calculated vapor–liquid equilibrium behavior for the R32 + R1234ze(E) binary system agreed with the experimental data collected from the open literature. The vapor-phase measurements were correlated through the aforementioned EoSs and a truncated virial EoS. These pvTz points agreed with both the values provided by the EoSs and REFPROP 10.0.

二氟甲烷+反式-1,3,3,3-四氟丙-1-烯二元体系的两相和汽相热物理性质(pvTz)测量

本文包含二氟甲烷(R32)和反式-1,3,3,3-四氟丙-1-烯(R1234ze )的混合物的182 pvTz数据(两相区域中的28数据和过热蒸汽区域中的154数据)(E))。测量沿10个等时线(0.013173、0.039422、0.043115、0.046522、0.062966、0.068225、0.068959、0.110447、0.115156和0.121732 m 3 ·kg –1进行10个R32摩尔分数(0.1677、0.2360、0.2551、0.4634、0.5374、0.6715、0.7383、0.7544、0.9532和0.9533)在263至373 K的温度范围内)。具有三个状态方程(EoSs)的闪蒸方法用于评估所分析的二元混合物的气液平衡。R32 + R1234ze(E)二元系统的计算的气液平衡行为与从公开文献中收集的实验数据一致。气相测量通过上述EoS和截短的病毒EoS进行关联。这些pvTz点与EoSs和REFPROP 10.0提供的值均一致。
