Abstract

The experimental solubility of dibenzofuran in modified supercritical carbon dioxide is measured at (318.2, 328.2, and 338.2) K in the (9 to 21) MPa pressure range using a built-in-house static view cell apparatus. CO2 is modified using methanol and acetic acid in the composition range of (3.5 to 5.5) mol %. Results are compared with those previously obtained for pure carbon dioxide, and the modifier effect is discussed. Solubility data obtained are correlated at each of the temperatures studied. The correlation equations may be used to predict the dibenzofuran solubility in methanol or acetic-acid-modified CO2 within the composition and pressure intervals studied or at values close to the interval limits. Results show the feasibility of using modified supercritical CO2 to extract dibenzofuran.
