ABSTRACT
The vapor pressure of dimethoxymethane was measured at temperatures from (283 to 398) K with pressures from (27.7 to 935.5) kPa, together with the vapor pressure of 1,1,1,3,3-pentafluorpropane (HFC-245fa) measured at temperatures from (253 to 403) K, with pressures from (19 to 2348) kPa. The vapor pressure data was then correlated using Wagner-type and Wu-type vapor pressure equations. The uncertainties of the measurements for temperature and pressure were within +- 5 mK and +- 0.7 kPa, respectively.
