Solubility of oxygen in liquid perfluorocarbons

The solubility of oxygen in several liquid perfluorocarbons was measured in the temperature range between 288 and 313 K and at pressures close to atmospheric. Values were measured with an apparatus based on the saturation method with an accuracy of ±1%. Thermodynamic functions such as Gibbs energy, enthalpy and entropy of solution were obtained from the composition and temperature dependence. The Peng–Robinson equation of state was used to model the gas solubility for the studied systems.
