ABSTRACT:
A process for treating a composition comprising one or more undesired compounds and one or more desired compounds so as to reduce the concentration of the one or more undesired compounds is described. The process comprises the steps of (1) contacting the composition with a solid adsorbent, (2) eluting the solid adsorbent on which the composition is retained with an extraction solvent comprising a (hydro)fluorocarbon, and (3) collecting a solvent eluate containing a composition having a reduced concentration of the undesired compounds from the solid adsorbent. The process is particularly suited to reducing the terpene content of an essential oil.
