Abstract

Supercritical carbon dioxide extraction of fragrances from jasmine flowers has facilitated higher recovery and better quality product than the conventional hexane extraction. Addition of a polar co-solvent to the CO 2 has rendered 200–600% enhancement in the fragrance recovery, the highest being with DMSO, and the lowest with methanol. Acetone enhances the solubility of cis-jasmone by 266% and enriches the product quality by offering the highest dissolution ratio enhancements for m-anthranilate and benzyl acetate, whereas with DMSO the dissolution ratio enhancements are the highest for other important fragrant components. Hence, a combination of the polar functional groups in the co-solvent as or equivalent to those of acetone and DMSO, seems to be most effective. With a view to selecting suitable co-solvents, the solubility enhancements of pure solids have been evaluated in terms of the interaction energy densities of the solute-co-solvent and solute-solvent specific interactions, which can, in turn, be predicted from the pure-component characteristic physical properties.
