The experimental equilibrium solubility of benzamide in supercritical carbon dioxide was measured at temperatures between 308K and 328K and for pressures from 11.0MPa to 21.0MPa using a dynamic flow method. The effects of three cosolvents – ethanol, acetone and ethylene glycol, were investigated at a cosolvent molar concentration of 3.5%. The results showed that the solubility was enhanced by the presence of the three cosolvents, and ethanol exhibited the highest cosolvent effect. The solubility data in the absence and presence of cosolvents were correlated by two density-based models. The calculated results showed satisfactory agreement with the experimental data.
