Fluid-liquid and liquid-liquid equilibria were measured for carbon dioxide-ethanol-water mixtures containing trace amounts of ethyl acetate, acetaldehyde, 2-pentanol, 1-propanol, diacetyl, acetic acid and methanol at temperatures near the critical temperature of carbon dioxide. Large separation factors were observed in the extraction of all the trace components except for acetic acid and methanol from ethanol aqueous solutions using supercritical or liquid carbon dioxide as solvent. The separation factor increased with increasing solvent density.<BR>A simple empirical model was developed to correlate the experimental data assuming the infinite dilution state for the trace components. The model correlates the separation factors with fairly good agreement with the experimental data.
