摘要 Extraction equilibria of three low volatility liquids (benzyl alcohol,2-phenethyl alcohol and citronellol)separately with supercritical CO<sub>2</sub> were determined in a semi-flow apparatus at two temperatures(308.2K and318.2K)and pressures up to 20MPa.The solubility data of CO<sub>2</sub> in methyl benzoate were also obtained at thetwo temperatures in two-phase region.The experimental data were correlated by means of the Peng-Robinsonequation of state with two characteristic parameters. Extraction equilibria of three low volatility liquids (benzyl alcohol, 2-phenethyl alcohol and citronellol) separately with supercritical CO2 were determined in a semi-flow apparatus at two temperatures (308.2K and 318.2K) and pressures up to 20MPa. The solubility data of CO2 in methyl benzoate were also obtained at the two temperatures in two-phase region. The experimental data were correlated by means of the Peng-Robinson equation of state with two characteristic parameters.
