Solubilities of several non-polar gases in mixtures water + 2,2,2-trifluoroethanol at 298.15 K and 101.33 kPa

Solubilities of nine nonpolar gases (H2, N2, O2, CH4, C2H6, C2H4, CF4, SF6, and CO2) in mixtures of water + 2,2,2-trifluoroethanol (TFE) at 298.15 K and 101.33 kPa partial pressure of gas are reported. A polynomial dependence of the solubilities on the mole fraction of the binary liquid mixture is found. The Henryʹs constants at the vapour pressure of water, the standard changes in the Gibbs energy for the solution process and for the solvation process, and the so-called excess Henryʹs constant are calculated. Gibbs energies for the solution process and excess Henryʹs constants have been calculated using the Scaled Particle Theory (SPT).
