Abstract

Abstract: Extraction equilibria of three low volatility liquids (benzyl alcohol,2-phenethyl alcohol and citronellol)separately with supercritical CO_2 were determined in a semi-flow apparatus at two temperatures(308.2K and318.2K)and pressures up to 20MPa.The solubility data of CO_2 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.

Key words: supercritical carbon dioide, low volatility liquid, phase equilibria
