• 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.

• 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.

• 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%.
