Fund Project: This work was supported by the National Natural Science Foundation of China and the Research Fund for the Doctoral Program of Higher Education (20076004,2000001005).

In this study, the constant volume, visual method is used to measure thc critical point of CO₂toluene, CO₂＋cyclohexane, CO₂＋n-butyraldehyde, CO₂＋i-butyraldchyde, CO₂＋methanol and CO₂＋alcohol binary systems. The relationship between critical point and the concentration of the entrainer for different substances has been discussed, and the comparison of the phase behavior of single component system and that of binary systems have been carried out.
- Critical point,
- supercritical,
- binary system,
- phase equilibrium
