Abstract (en)

[origin: EP0363971A2] A process for removing terpenes from essential oils is described and entails a) the terpene-containing essential oils being contacted with a polar solid (adsorbent), b) the loaded adsorbent being separated from the liquid phase enriched in terpenes, and c) the adsorbent loaded with essential oil being extracted with condensed CO2. <??>It is possible in this way substantially to remove the terpenes and, at the same time, to obtain the essential oils in high yield and good quality.
