在温度为235.69~372.14 K，压力为0.1015~4.7139 Mpa的条件下，测定了氟乙烷的蒸汽压。在本工作中，压力的最大不确定度为±1.5kPa，温度的最大不确定度为±6mK。用瓦格纳型方程对110个实验点的蒸汽压进行了拟合。并将新的氟乙烷蒸气压方程与现有文献数据进行了比较。本测量中使用的HFC-161样品的纯度为99.74质量%。
The vapor pressures of ethyl fluoride (HFC-161) were measured at temperatures from (235.69 to 372.14) K and corresponding pressures from (0.1015 to 4.7139) MPa. The maximum uncertainties in the present work were estimated to be ± 1.5 kPa for pressure and ± 6 mK for temperature. The 110 experimental data points taken for the vapor pressure were fitted with a Wagner-type equation. The new vapor pressure equation of ethyl fluoride was also compared with available literature data. The purity of the HFC-161 sample used in the present measurements was 99.74 mass %.
