2-Octanone Usage And Synthesis
- Description2-octanone is a kind of natural ketone found in many sources such as coco, baked peanuts, potato, cheese, beer, banana and oranges. It can be used as a flavor and fragrance ingredient. It is used in the field of fiber, medicine, pesticides and spices for the synthesis of fiber oil, defoamer and the preparation of surfactants, coal flotation agent.

- Description2-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.

- OccurrenceReported 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.
- UsesPerfumes, high-boiling solvent, especiallyfor epoxy resin coatings, leather finishes, flavor-ing, odorant, antiblushing agent for nitrocelluloselacquers.
- DefinitionChEBI: A methyl ketone that is octane substituted by an oxo group at position 2.
- Production Methods2-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%.
- PreparationBy 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 valuesDetection: 41 to 62 ppb
- Taste threshold valuesTaste characteristics at 10 ppm: dairy, waxy, cheese, woody, mushroom and yeast.
- Industrial usesMethyl 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.
- Safety ProfilePoison 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.
