PROCEDE D'EXTRACTION OU DE FRACTIONNEMENT PAR FLUIDE SUPERCRITIQUE EN PRESENCE D'UN CO-SOLVANT INCLUANT AU MOINS UN SOLVANT FLUORE |
摘要 |
The invention concerns an extraction and/or fractionation method with supercritical fluid comprising steps which consist in: contacting a raw material containing one or more compounds to be extracted with a fluid in supercritical state in the presence of at least a cosolvent; lowering the pressure of the mixture formed by the fluid in supercritical state, said cosolvent and said compound(s) extracted from said raw material so as to recuperate said fluid in gaseous state and said cosolvent containing said extracted compound(s). The invention is characterised in that the cosolvent consists at least partly of a fluorinated solvent.
