ABSTRACT
Vapor pressure of dimethyl ether was measured using a modified constant volume apparatus. Measurements were carried out at temperatures from (213 to 393) K and at pressures from (16 to 4706) kPa. A total of 39 experimental points were obtained with uncertainties of ( 5 mK on ITS-90 for temperature and ( 0.7 kPa for pressure. The measurement results were fitted to a Wagner-type equation with an average absolute deviation of 0.033 %. Also, the new vapor pressure equation was compared with the published data.
