Solubility of gases in fluoroorganic alcohols Part I. Solubilities of several non-polar gases in 1,1,1,3,3,3-hexafluoropropan-2-ol at 298.15 K and 101.33 kPa

Abstract

Solubility measurements of several non-polar gases (He, Ne, Ar, Kr, Xe, H₂, N₂, O₂, CH₄, C₂H₄, C₂H₆, CF₄, SF₆ and CO₂) in 1,1,1,3,3,3-hexafluoropropan-2-ol (HFIP) at 298.15 K and 101.33 kPa partial pressure of gas are reported. The experimental values of the solubility of gases are expressed as mole fractions of gas. They are used to obtain the Gibbs energy for the solution process whose values are then compared with those previously obtained for 2,2,2-trifluoroethanol (TFE). Parameters for a Lennard–Jones 6–12 additive potential for repulsive and dispersive forces between the solvent molecules are also estimated by using the scaled particle theory (SPT), and then applied to calculate theoretical solubilities which are checked with the experimental values.
