Experiences with Solid C0₂ Concentration of Bergamot Cold-Pressed Essential Oil (Citrus bergamia Risso)

Abstract

Sublimation of solid CO₂, selectively removed hydrocarbons from bergamot oil. This result was achieved in a laboratory with very simple equipment. The oil and dry ice were mixed in a cylindrical vessel and the gas stream entrained most of non-oxygenated terpenes. Their behavior is discussed briefly.
