化学的特性
Dihydromyrcenol is a colorless liquid with a
fresh citrus-like odor and a lavender note. It is obtained from 3,7-dimethyl-1,6-
octadiene (citronellene), the pyrolysis product of cis-pinane and can be prepared by three different processes: (i) by addition of hydrogen chloride and
subsequent hydrolysis of the resulting 2,6-dimethyl-2-chloro-7-octene; or
(ii) by addition of formic acid and subsequent saponification of the resulting
dihydromycrenyl formate; or (iii) by direct hydroxylation with 60–80%
sulfuric acid.Dihydromyrcenol is used in fine fragrances as well as in soap and detergent perfumes
for fresh lime and citrus-like floral notes.
天然物の起源
Found in the leaf oils of Barosma venusta and in the oil of hops (Gildemeister & Hoffman, 1960)
使用
Dihydromyrcenol is used in the fragrance industry for its fresh lime and citrus-like odor.
Dihydromyrcenol is a fragrance ingredient used in cosmetics, fine fragrances, shampoos, toilet soaps, and other toiletries as well as in non-cosmetic products such as household cleaners and detergents. Its worldwide use is greater than >1000 metric tons per year (IFRA, 2004). A colorless, somewhat viscous liquid that is a mixture of approximately 50% 2,6-dimethyl-7-octen-2-ol and 50% 2,6-dimethyl-7-octen-2-yl formate. It has apparently not been reported to occur in nature.
定義
ChEBI: A monoterpenoid that is oct-7-en-2-ol substituted by methyl groups at positions 2 and 6 respectively.
製造方法
Dihydromyrcenol is prepared by adding hydrogen chloride to myrcene followed by hydrolysis under mild conditions.(Bedoukian, 1967)
