A constant-volume visual cell was used to measure vapor-liquid phase equilibrium data of 2-butanol in supercritical carbon dioxide from 323.2K to 353.2K. The phase equilibrium solubilities were predicted by Peng-Robinson equation of state together with Vander Waals-2 mixing regulation. Dependence of solubility of CO2 in liquid 2-butanol on pressure was discussed by Krichevsky-kasarnovsky equation. Meanwhile, Henry’s constants and partial molar volume at infinite dilution were determined. Also partial molar volumes of vapor phase and liquid phase at equation state were evaluated from proposed model. The correlation between calculated values and the experimental data showed good agreement.
