Terpinyl acetate Usage And Synthesis
  • Chemical PropertiesColorless liquid; odor suggestive of bergamot and lavender. Soluble in five or more volumes of 70% alcohol; slightly soluble in water and glycerol. Combustible.
  • Chemical PropertiesThe enantiomers and the racemate occur in many essential oils (e.g., Siberian pine-needle oil and cypress oil), but generally not as the main component. Pure Terpinyl acetate are colorless liquids with a fresh bergamot–lavender odor. Commercially available terpinyl acetate consists mainly of alpha-terpinyl acetate, but also contains a number of other isomeric compounds such as beta-terpinyl acetate. It can be prepared by acetylating the terpineol mixture obtained from terpin hydrate, using a customary procedure for tertiary alcohols.
    Because of its odor properties, stability, and low price, large quantities of terpinyl acetate are used in perfumery for lavender and bergamot types, as well as in essential oil reconstitutions.
  • OccurrenceReported in over 40 essential oils, including cypress, Malabar cardamom, cajeput niaouli, Siberian pine needles, pine, Melaleuca trichostachya, Melaleuca pauciflora and others; also identified in the essential oils of bitter orange (Fenarolfs Handbook of Flavor Ingredients, 1971 ; Gildemeister & Hoffman, 1966).
  • UsesPerfumes, flavoring agent.
  • PreparationBy acetylation of a-terpineol or mixed isomeric terpineols (Bedoukian, 1967).
  • Synthesis Reference(s)Tetrahedron, 38, p. 1843, 1982 DOI: 10.1016/0040-4020(82)80261-5
  • Safety ProfileMildly toxic by ingestion. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.
