The exhaustive extraction with n-hexane performed at the solvent boiling point during 20 h indicated an extraction yield of 52.6% in relation to the raw material fed into the reactor (standard deviation of 1.6% based on three replicates runs). The effect of density and temperature in the extraction with carbon dioxide as solvent indicated that both variables present positive effect on the extraction yield. The comparison of runs 1 and 2 at 313K and runs 3 and 4 at 333K suggests that the increase in density at fixed temperature promotes the enhancement in the extraction yield.
