Abstract :
p I" T data Ibr liquid 2-lluoroethanol (FE) have been obtained in the Ibrm of
volume ratios at six temperatures (278.15, 288.15, 298.14, 313.14, 323.14, and
338.130K) at pressures from atmospheric to 314MPa or higher. Freezing
pressures have also been measured in the temperature range from the normal
freezing point to 288 K. Densities at atmospheric pressure in the same temperature
range as that liar the p 1ʹ T data are also reported. Isothermal compressibilities.
isobaric expansivities, changes in the isobaric heat capacity, and internal pressures
have been calculated from the volumetric data. Representation of the volume
ratios for FE, 2,2-dilluoroethanol, 2,2,2-trifluoroethanol, and ethanol by a form of
the modilied Tait equation shows that the effect of the progressive substitution of
Iluorine into ethanol cannot be represented by a simple correlation.
