The vapor–liquid equilibria for the binary systems difluoromethane (R32) + trans-1,1,1,4,4,4-hexafluoro-2-butene (R1336mzz(E)) and fluoroethane (R161) + trans-1,1,1,4,4,4-hexafluoro-2-butene (R1336mzz(E)) have been investigated using a liquid recirculation apparatus from 283.17 to 333.06 K and 283.12 to 333.00 K, respectively. The experimental data were correlated by the PR + WS + NRTL model. The correlated results showed good agreement with the experimental results for the two binary mixtures. The average absolute relative deviation of pressure (AARDp) and average absolute deviation of vapor composition (AADy) were 0.88% and 0.003 for R32 + R1336mzz(E) and 0.86% and 0.005 for R161 + R1336mzz(E), respectively. These systems exhibited no azeotropic behavior within the investigated temperature range. Also, the relative volatilities α₁₂ for the two mixtures were further obtained and correlated by the PR +WS +NRTL model. The results showed that the correlated results had good agreement with the experimental results, and the deviations were less than 4.3 and 7.2% for R32 + R1336mzz(E) and R161 + R1336mzz(E), respectively.

二氟甲烷 (R32) +反式-1,1,1,4,4,4-六氟-2-丁烯 (R1336mzz(E)) 和氟乙烷 (R161) +反式-1,1二元系统的汽液平衡,1,4,4,4-六氟-2-丁烯 (R1336mzz(E)) 分别使用液体再循环装置从 283.17 到 333.06 K 和 283.12 到 333.00 K 进行了研究。实验数据通过 PR + WS + NRTL 模型进行关联。相关结果与两种二元混合物的实验结果非常吻合。压力的平均绝对相对偏差 (AARD p ) 和蒸气成分的平均绝对偏差 (AAD y) 对于 R32 + R1336mzz(E) 分别为 0.88% 和 0.003，对于 R161 + R1336mzz(E) 分别为 0.86% 和 0.005。这些系统在研究的温度范围内没有表现出共沸行为。此外，通过PR+WS+NRTL模型进一步获得并关联了两种混合物的相对挥发度α ₁₂。结果表明，相关结果与实验结果吻合较好，R32+R1336mzz(E)和R161+R1336mzz(E)的偏差分别小于4.3%和7.2%。
