310～420K,200MPaまでの領域におけるトリフルオロエタノール水溶液の熱力学性質の組成依存性

The vapor-liquid-equilibrium and thermodynamic properties of aqueous mixtures of 2, 2, 2-trifluoroethanol have been studied as a function of composition based on the experimental results of bubble pressures, saturated liquid densities and PVTX properties for seven mixtures in the temperature range from 310 K to 420 K at pressures up to 200 MPa. The composition dependence of bubble pressures, saturated liquid densities, excess molar volumes, isothermal compressibilities and isobaric expansivities is reported. The behavior of these properties is discussed on the basis of the inter molecular forces.
