Abstract
Solubilities, expressed as mol fractions, of 14 nonpolar gases (He, Ne, Ar, Kr, Xe, H2, N2, O2, CH4, C2H4, C2H6, CO2, CF4, and SF6) in 2,2,2-trifluoroethanol (TFE) at 268.15 and 283.15 K and 1,1,1,3,3,3-hexafluoropropan-2-ol (HFIP) at 273.15 and 283.15 K, with the partial pressure of gas being 101.33 kPa for all measurements, are reported. Standard changes in the thermodynamic functions (enthalpy and entropy) have been calculated from the solubilities and their variation with temperature. The Scaled Particle Theory (SPT) model has been used to determine these thermodynamic functions and also the partial molar volumes of the gases in the formed solutions.Key words: gas solubilities, nonpolar gases, fluoroalcohols, Scaled Particle Theory.
