Solubility of oxygen in liquid perfluorocarbons

resumo

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. (C) 2004 Elsevier B.V. All rights reserved.
