3-옥타논 C화학적 특성, 용도, 생산
개요
3-Octanone has a strong, penetrating, fruity odor reminiscent of
lavender. It can be prepared by passing a mixture of vapors of
caproic acid and acetic acid over ThO2 at 400°C, or by oxidation
of d-ethyl n-amyl carbinol with chromates; another synthetic route
is reported.
화학적 성질
3-Octanone has a strong, penetrating, fruity odor reminiscent of lavender.
출처
Reported identified in the low-boiling fraction of the essential oil of lavender; also reported found in the
essential oils of Lavandula vera (10%) and French lavender. Reported found in banana, bilberry, currants, guava, melon, blueberry,
blackberry, strawberry jam, peas, fried potato, ginger, Mentha oils, thyme, cheeses, butter, fish, cooked meats, cognac, coffee, tea,
roasted peanuts, pecan, soybean, olive, plum, beans, mushroom, wild marjoram, trassi, rice bran, litchi, calamus, buckwheat, rosemary,
lemon balm, clary sage, rosemary, truffle, nectarine, anise hyssop and maté.
용도
3-Octanone can be produced by oxidation of 3-octanol or by
heating propionic acid and caproic acid over thorium oxide.
3-Octanone is used as an ingredient in soaps, perfumes,
lotions, and creams. It is also used as a flavoring agent in
foods. U.S. production and importation of 3-octanone was
estimated to be relatively low (,25,000 lb at a single site) in
2005 as data for 3-octanone were not included in the 2006
U.S. EPA Inventory Update Reporting database.
제조 방법
By heating propionic and caproic acids over thorium oxide or by oxidation of ethyl amyl carbinol (3-octanol) (Arctander, 1969).
일반 설명
A clear colorless liquid with a pungent odor. Insoluble in water and partially soluble in alcohol. Flash point of 138°F. Vapors are denser than air and may have a narcotic effect in high concentrations. Used in making perfumes and as a solvent for nitrocellulose and vinyl resins.
공기와 물의 반응
Flammable. Insoluble in water.
반응 프로필
Ketones, such as 3-Octanone, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.
위험도
Narcotic in high concentration. Moderate
fire risk.
건강위험
May be harmful by inhalation, ingestion or skin absorption. Vapor or mist is irritating to eyes, mucous membrane and upper respiratory tract. Causes skin irritation.
화재위험
Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flash back.
Safety Profile
Poison by
intraperitoneal route. Moderately irritating to
skin, eyes, and mucous membranes by
inhalation. Narcotic in high concentration.
Flammable liquid when exposed to heat,
sparks, flame, or oxidizers. To fight fire, use
foam, CO2, dry chemical. When heated to
decomposition it emits acrid smoke. See also
KETONES.
