New results of vapor pressure are presented for tetraethylene glycol dimethyl ether (TEGDME) and 2,2,2-trifluoroethanol (TFE) in the ranges of temperatures from 373.15 to 533.15 K, and 293.15 to 363.15 K, respectively. Measurements were made using the static method. The static vapor pressure apparatus developed is described. For the practical utility, vapor pressure data for TEGDME were fitted to Antoine equation and for TFE to a Wagner-type equation, combining in this case the experimental data with those of Sauermann et al. (1993) to cover a wide temperature range.
