Experimental vapor pressure data and a vapor pressure equation for N,N-dimethylformamide
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 %.
