化学的特性
CIVETONE is a colorless
liquid with warm, sensual, animalic musky odor and extreme tenacity. It is
themain odoriferous constituent of civet.Civetonewas formerly prepared bymultistep
syntheses, for example. Recently, newer processes using dimethyl
(Z)-9-octadecendioate as starting material have been described. This is cyclized
by a Dieckmann condensation either in liquid or in gaseous phase.
(Z)-9-Octadecendioic acid is available by microbial oxidation of oleic acid with
Candida tropicalis.
It is used in fine fragrance compositions for, for example, toiletries and body
care products.
