化学的特性
Ethyl Hexanoate is a colorless liquid
with a strong fruity odor, reminiscent of pineapples. It occurs in many fruits and
is used in small amounts for floral, fruity notes in perfume compositions and in
larger quantities in fruit flavors.
天然物の起源
Reported found in strawberry, rum, bourbon, cocoa, kiwi fruit, black currant, apple, orange and grapefruit
juice, guava, Vitis vinifera, pineapple, strawberry jam, clove bud, cheeses, cognac, whiskies, grape wines, passion fruit juice, mango,
fruit brandies, figs, corn oil, mountain papaya, pawpaw and mastic gum leaf oil.
使用
Ethyl hexanoate may be used as an analytical reference standard for the determination of the analyte in wine and beer samples by chromatography based techniques.
定義
ChEBI: A fatty acid ethyl ester obtained by the formal condensation of hexanoic acid with ethanol.
製造方法
By esterification of caproic acid with ethyl alcohol in the presence of concentrated H2SO4 or HCl
一般的な説明
Ethyl hexanoate is one of the odorants contributing to the typical guava aroma. It also contributes to the fresh strawberry aroma.
安全性プロファイル
A skin irritant.
Flammable liquid when exposed to heat or
flame; can react with oxidzing materials.
When heated to decomposition it emits
acrid smoke and irritating fumes. To fight
fire, use CO2, foam, dry chemical. See also
ESTERS.
発がん性
Not listed by ACGIH, California
Proposition 65, IARC, NTP, or OSHA.
代謝
Aliphatic esters, including ethyl caproate, are thought to be readily hydrolysed to the corresponding alcohol and acid, which are then further metabolized (Fassett, 1963). Ethyl caproate administered orally to rats produced a uniform ketonuria and it was considered probable that caproic acid was broken down chiefly by ?-oxidation (Deuel, Hallman, Butts & Murray, 1936). When 2 g ethyl caproate dissolved in aqueous ethanol was fed directly into the rumen of a cow, 0.003°/ was transferred to the milk, reaching a maximum level of 60 /fg/litre after 2-4 hr (Honkanen, Karvonen & Virtanen, 1964). The energy from ethyl caproate was 52% available when the ester was fed to four chicks at a level of 5% in the diet (Yoshida et al. 1970).
