Phase equilibrium measurements have been carried out over a range of temperatures and pressures on four mixtures of soybean oil deodorizer condensates with supercritical CO2. These complex mixtures are not available in nature, but are produced during separation processes. They are different in composition and cover a wide concentration range. Samples from both liquid and vapor phase were taken and analyzed by GC. Tocopherols, sterols and squalene were identified. Additional components were grouped into pseudocomponents. Distribution coefficients were calculated from the experimental data and the influence of temperature and composition is discussed for these complex systems. Pseudobinary data for one mixture are correlated using the Hederer-Peter-Wenzel modification of the Redlich Kwong equation of state with either Van der Waals or Melhem mixing rules. Fitting of interaction parameters leads to good agreement with experimental data.
