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.

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.
