n-노난올 C화학적 특성, 용도, 생산
개요
1-Nonanol is a straight chain fatty alcohol with nine carbon atoms and the molecular formula CH3(CH2)8OH. It is a colorless to slightly yellow liquid with a citrus odor similar to citronella oil. Nonanol occurs naturally in the orange oil. The primary use of nonanol is in the manufacture of artificial lemon oil. Various esters of nonanol, such as nonyl acetate, are used in perfumery and flavors. Nonanol floats on water and its freezing point 23°F.
화학적 성질
1-Nonanol is a colourless to light yellow liquid that has a characteristic rose-orange odor and a slightly fatty, bitter taste reminiscent of orange. It can be found in several citrus oils.
출처
Reported as occurring frequently in nature, free or esterified; in the essential oils of grapefruit, Guinea sweet
orange, Italian and Israeli sweet orange, bitter orange; and in oak musk concrete. Also reported found in apple, citrus juices, many
berries, currants, guava, grapes, papaya, melon, pineapple, asparagus, cucumber, leek, peas, potato, cheeses, butter, milk, cooked
chicken, beef and pork, hop oil, beer, rum, grape wines, tea, pecan, peanut oil, soybean, olive, plum, rose apple, beans, mushroom,
starfruit, cauliflower, tamarind, fig, cardamom, rice, prickly pear, sweet corn, malt, cherimoya, clary sage, oysters, crab, crayfish,
clam, nectarine, mate, pepino fruit (Solanum muricatum), apricot, tobacco, and wheat bread.
생산 방법
1-Nonanol is produced by the high-pressure catalytic reduction
of esters of pelargonic acid.
제조 방법
1-Nonanol can be synthesized by reduction of ethyl pelargonate; from heptaldehyde via heptanol and heptylmagnesium bromide with ethylene oxide.
일반 설명
Colorless liquid with a rose or fruity odor. Floats on water. Freezing point 23°F.
반응 프로필
1-Nonanol is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
건강위험
Liquid irritates eyes.
Safety Profile
Mddly toxic by
ingestion, skin contact, and inhalation.
Experimental reproductive effects.
Combustible liquid. When heated to
decomposition it emits acrid smoke and
irritating fumes. See also ALCOHOLS.
신진 대사
See alcohol C-8. Nonanol, like other primary alcohols, undergoes two general reactions in vivo. The first is oxidation to the carboxylic acid derivative and next the direct conjugation with glucuronic acid. It was reported that nonanol undergoes direct glucuronic conjugation to the extent of 4.1%. This oxidation proceeds with very little inhibition as opposed to that shown by methyl amyl alcohol and 2-ethyl butyl alcohol which form ester glucuronides.
