N,N-二甲基甲酰胺 (DMF) 蒸气压数据的新结果已在 (308.15 至 368.15) K 的温度范围内测量。目前工作中的测量不确定度估计在温度 +/- 10 mK 和压力 +/- 0.103 kPa 范围内。基于实验数据，提出了新的DMF瓦格纳型蒸气压方程。 DMF 方程也与现有文献数据进行了比较。本测定中使用的DMF样品的纯度为99.99质量%。
New results of vapor pressure data for N,N-dimethylformamide (DMF) have been measured in the range of temperatures from (308.15 to 368.15) K. The measurement uncertainties in the present work were estimated to be within +/- 10 mK for temperature and +/- 0.103 kPa for pressure. Based on experimental data, a new Wagner-type vapor pressure equation for DMF was presented. The equation of DMF was also compared with available literature data. The purity of DMF sample used in the present measurements was 99.99 mass %.
