摘要：

Eighty-six measurements of the vapor pressure of 2,2,2-trifluoroethanol (TFE) have been obtained by the static method at intervals of 5 K in the temperature range from 320 K to 400 K. The experimental uncertainties of temperature and pressure measurements have been estimated as ±6 mK and ±0.6 kPa, respectively. The reproducibility of the present measurements at the same temperature is almost within ±0.4 kPa. The present results were fitted to a function of temperature with a standard deviation of 0.31 kPa. The temperature at 101.325 kPa on the vapor-pressure curve, i.e. the normal boiling temperature, of TFE is determined as (347.04±0.10) K. The effect of remaining air and water in the sample for the vapor-pressure measurements is discussed quantitatively. © 1991 Academic Press Limited All rights reserved.
