| Abstract: | The use of cosolvents enlarges the application of supercritical fluids and speeds up the progress of the science and technology of supereritical fluids. The research of cosolvent effects in supereritical fluids using the technique of phase behavior, calorimetry, spectrum and molecular simulation are reviewed from the view of phase behavior and thermodynamics of the intermolecular interactions. The research on mechanism of cosolvent effects and the thermodynamic properties of mixed fluids near the critical point are introduced, the developiug trend of cosolvent effects and mixed fluid is prospected. |
