Beschreibung
2-Octanone has a floral and bitter, green, fruity (unripe apple) odor with a bitter camphoraceous taste. May be synthesized by the oxidation of methyl hexyl carbinol with K2Cr2O7 and sulfuric acid; also by oxidation of 2-octanol over zinc oxide at 330 - 340°C.
Chemische Eigenschaften
Colorless liquid; pleasant odor; cam-phor taste. Insoluble in water; solublein alcohol, hydrocarbons, ether, esters, etc. Com-bustible.

Verwenden
2-Octanone is used in perfumes, high-boiling solvent, especially for epoxy resin coatings and in leather finishes. It is used in flavoring, odorant. It can act as antiblushing agent for nitrocellulose lacquers.
Verwenden
2-Octanone may be used as an analytical reference standard for the quantification of the analyte in sugar-cane spirits and rum samples and whey protein concentrate using chromatography based techniques.
Definition
ChEBI: A methyl ketone that is octane substituted by an oxo group at position 2.
Vorbereitung Methode
2-Octanone can be produced by oxidation of methyl hexyl carbinol, 2-octanol, or 1-octene or by reductive condensation of acetone with pentanol. Commercial samples can have a purity of 98%.
synthetische
By oxidation of methyl hexyl carbinol with K2Cr2O7 and sulfuric acid; also by oxidation of 2-octanol over zinc oxide at 330 to 340°C.
Aroma threshold values
Detection: 41 to 62 ppb
Taste threshold values
Taste characteristics at 10 ppm: dairy, waxy, cheese, woody, mushroom and yeast.

Allgemeine Beschreibung
2-Octanone is a volatile flavor compound reported to be found in blue cheese, acerola fruit, blue crab and cray fish.
Industrielle Verwendung
Methyl n-hexyl ketone is used as solvent for vinyl compounds and dyes and is suitable for dispersing dyes in light-weight petroleum oils for newsprint inks.
Sicherheitsprofil
Poison by ingestion. Moderately toxic by intraperitoned route. A sktn irritant. Flammable liquid when exposed to heat, flame, or oxidizers. To fight fire, use foam, alcohol foam. When heated to decomposition it emits acrid smoke and irritating fumes. See also ETHER and KETONES.
