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

2-Octanone has a floral and bitter, green, fruity (unripe apple) odor and bitter, camphoraceous taste. Insoluble in water; solublein alcohol, hydrocarbons, ether, esters, etc. Com-bustible.

Occurrence

Reported found in apple, apricot, banana, cranberry, grape, raisin, papaya, peach, raspberry, strawberry, leek, peas, clove, wheat bread, many cheeses, butter, milk, cooked egg, yogurt, caviar, fatty fish, meats, beer, hop oil beer, cognac, rum, grape wines, cocoa, coffee, tea, roasted filberts and peanuts, pecans, potato chips, oats, soybean, olive, beans, walnut, trassi, mushroom, fig, rice, buckwheat, quince, sweet corn, corn oil, malt, wort, krill, Bourbon vanilla, mountain papaya, shrimp, crab, crayfish, clam, truffle, maté and mastic gum oil.

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.

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.

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%.

Definition

ChEBI: A methyl ketone that is octane substituted by an oxo group at position 2.

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.
