• Beschreibung

  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.

  CLEAR COLOURLESS TO SLIGHTLY YELLOW LIQUID

• Occurrence

  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.

• Verwenden

  3-Octanone was used to study the effect of TiO2 photo catalyst on the rate and the ratio of products generated in photo catalytic oxidation of 3-octanone. It is used as a flavor and fragrance ingredient.

• Verwenden

  Perfumery, solvent for nitrocellulose and vinyl resins.

• Verwenden

  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.

• synthetische

  By heating propionic and caproic acids over thorium oxide or by oxidation of ethyl amyl carbinol (3-octanol) (Arctander, 1969).

• Definition

  ChEBI: 3-octanone is a dialkyl ketone that is octane in which the two methylene protons at position 3 have been replaced by an oxo group. It has a role as a human urinary metabolite, an insect attractant, a fungal metabolite, an antifeedant, a plant metabolite and a biomarker. It derives from a hydride of an octane.

• Aroma threshold values

  Detection: 21 to 50 ppb

• Taste threshold values

  Taste characteristics at 10 ppm: mushroom, ketonic, cheesy and moldy with a fruity nuance.

• Allgemeine Beschreibung

  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.

• Air & Water Reaktionen

  Flammable. Insoluble in water.

• Reaktivität anzeigen

  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.

• Hazard

  Narcotic in high concentration. Moderate fire risk.

• Health Hazard

  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.

• Brandgefahr

  Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flash back.

• Biochem/physiol Actions

  Taste at 10 ppm

• Sicherheitsprofil

  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.

• Synthese

  It can be prepared by passing a mixture of vapors of caprioc 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.
