In this work, 91 vapor pressure data of cis-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz(Z)) were measured using a Burnett apparatus in a temperature range of (278 to 443) K and a pressure range of (30 to 2830) kPa. The sample was analyzed by gas chromatography with mass spectrometry, and the vapor pressure deviations caused by impurities were corrected based on the ideal solution model. The combined expanded (k = 2) uncertainty in the temperature measurement is 6.2 mK, and the combined expanded (k = 2) uncertainty in vapor pressure is (0.30 to 0.90) kPa. On the basis of the literature data and the experimental data in this work, a new Wagner-type vapor pressure equation was used to correlate the experimental data. The normal boiling point temperature of HFO-1336mzz(Z) was estimated to be 306.613 K.

cis-1,1,1,4,4,4-六氟-2-丁烯（HFO-1336mzz（Z））的蒸气压测量及相关

在这项工作中，使用Burnett仪器在（278至443）K，压力范围为（30至2830）kPa。通过气相色谱-质谱法分析样品，并基于理想溶液模型校正由杂质引起的蒸气压偏差。温度测量中的组合扩展（k = 2）不确定度为6.2 mK，组合扩展（k= 2）蒸气压的不确定度为（0.30至0.90）kPa。在这项工作的文献数据和实验数据的基础上，使用了一个新的Wagner型蒸气压方程来关联实验数据。HFO-1336mzz（Z）的正常沸点温度估计为306.613K。
