Bornyl acetate Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften
Bornyl acetate has a fresh, strong, piney odor and a fresh, burning taste.
Chemische Eigenschaften
Bornyl acetate occurs in its optically active forms and as a racemate in many essential oils.
(1S,2R,4S)-(?)-Bornyl acetate is a characteristic component of most conifer oils. It has a camphoraceous, pine-needle-like odor. Both (1R,2S,4R)- (+)-bornyl acetate and (?)-bornyl acetate form colorless crystals; the racemate is a colorless liquid. Bornyl acetate is prepared by esterification of borneol with acetic anhydride or via the process described under borneol.
Due to its characteristic pine-needle odor, bornyl acetate is frequently used in conifer needle compositions, soaps, bath products, room sprays, and pharmaceutical products.
Occurrence
Reported found in the oils of Abies canadensis, A. concolor, Picea canadensis, P. rubens, P. orientalis, Pinus densiflora, Larix americana, Callitris drum-mondi, Abies alba, Pinus punulio, Abies sibirica L., and in coriander, thyme and valerian oil; it has been identified in the essence from flowers of Chrysanthemum sincuse Sabin, in the distillate of Teucrium chamaedris L., and in the fresh rhizomes of Valeriana officinalis L.; d-bornyl acetate is found in the essential oils of Callitris glauca, C. robusta, C. gracilis, C. verrucosa and C. calcarata; the presence of acetate has been excluded from the essence of lavender and lavandin.
Verwenden
Antineoplastic; radioactive agent.
Aroma threshold values
Detection: 75 ppb to 1.38 ppm
Taste threshold values
Taste characteristics at 10 ppm: camphoreous, woody, mentholic, berry and seedy with soapy, woody nuances.
Synthese
l-Bornyl acetate occurs naturally in many oils distilled from the leaves of plants of the family Pinaceae; d-bornyl acetate is found in the oils distilled from plants of the family Cupressaceae; bornyl acetate, therefore may be isolated by distillation and crystallization from these; however, it is commonly prepared by direct acetylation of borneol; the first synthesis dates to 1889.
