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

Solubility measurements of several non-polar gases (He, Ne, Ar, Kr, Xe, H-2 , N-2, O-2, CH4, C2H4, C2H6, CF4, SF6 and CO2) in 1,1,1,3,3,3-hexafluoropro pan-2-ol (HFIP) at 298.15 K and 101.33 kPa partial pressure of gas are repo rted. The experimental values of the solubility of gases are expressed as m ole fractions of gas. They are used to obtain the Gibbs energy for the solu tion process whose values are then compared with those previously obtained for 2,2,2-trifluoroethanol (TFE). Parameters for a Lennard-Jones 6-12 addit ive potential for repulsive and dispersive forces between the solvent molec ules are also estimated by using the scaled particle theory (SPT), and then applied to calculate theoretical solubilities which are checked with the e xperimental values.
