Solubility Of Nonpolar Gases

Solubility measurements of several nonpolar gases (He, Ne, Ar, Kr, Xe, H2, D2, N2, CH4, C2H4, C2H6, CF4, SF6, and CO2) in 2-methylcyclohexanone at 273.15–303.15 K and a partial pressure of gas of 101.32 kPa are reported. Thermodynamic functions (Gibbs energy, enthalpy, and entropy) for the solution process at 298.15 K and 101.32 kPa partial pressure of gas are evaluated. Use is made of the Scaled Particle Theory applied to gas solubility for determining Lennard-Jones (6, 12) pair-potential parameters and temperature dependence of the effective hard-sphere diameter of the solvent. The values that this theory predicts for the solution thermodynamic functions are also calculated. Keywords: 2-methylcyclohexanone, gas solubility, thermodynamic functions of solution, Henry coefficient, scaled particle theory.

Solubility Of Nonpolar Gases

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.
