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

Abstract

2-ol) at the temperature of 298.15 K and 101.33 kPa partial pressure of gas are reported. A polynomial dependence of the solubilities on the molar fraction of the binary liquid mixture is found. The Henry's constants at the vapor pressure of water, the standard changes in the Gibbs energy for the solution process and for the solvation process, and the so-called excess Henry's constant are calculated. The results have been compared with those obtained by scaled particle theory (SPT). A method to compare the solubility of a gas in different liquids is proposed and applied to 2,2,2-trifluoroethanol and 1,1,1,3,3,3-hexafluoropropan-2-ol.
