This paper reports on a complex phenolic mixture successfully extracted from an aqueous solution by using near-critical and supercritical carbon dioxide, with and without entrainers. Experimental extractions were performed at 298 and 323 K at pressures up to 27.6 MPa to measure distribution coefficients. The Peng-Robinson equation of state with a recently published mixture combining rule quantitatively modeled the system and provided a qualitative prediction of the effect of adding a small amount of benzene as an entrainer.
