3-Octanone Usage And Synthesis


Description

3-Octanone has a strong, penetrating, fruity odor reminiscent of lavender. It can be prepared by passing a mixture of vapors of caproic acid and acetic acid over ThO2 at 400°C, or by oxidation of d-ethyl n-amyl carbinol with chromates; another synthetic route is reported.

Chemical Properties

3-Octanone has a strong, penetrating, fruity odor reminiscent of lavender.

Chemical Properties

CLEAR COLOURLESS TO SLIGHTLY YELLOW LIQUID

Uses

3-Octanone can be produced by oxidation of 3-octanol or by heating propionic acid and caproic acid over thorium oxide. 3-Octanone is used as an ingredient in soaps, perfumes, lotions, and creams. It is also used as a flavoring agent in foods. U.S. production and importation of 3-octanone was estimated to be relatively low (,25,000 lb at a single site) in 2005 as data for 3-octanone were not included in the 2006 U.S. EPA Inventory Update Reporting database.

Uses

Perfumery, solvent for nitrocellulose and vinyl resins.

Aroma threshold values

Detection: 21 to 50 ppb

Taste threshold values

Taste characteristics at 10 ppm: mushroom, ketonic, cheesy and moldy with a fruity nuance.

General Description

A clear colorless liquid with a pungent odor. Insoluble in water and partially soluble in alcohol. Flash point of 138°F. Vapors are denser than air and may have a narcotic effect in high concentrations. Used in making perfumes and as a solvent for nitrocellulose and vinyl resins.

Air & Water Reactions

Flammable. Insoluble in water.

Reactivity Profile

Ketones, such as 3-Octanone, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.

Hazard

Narcotic in high concentration. Moderate fire risk.

Chemical Synthesis

It can be prepared by passing a mixture of vapors of caprioc acid and acetic acid over ThO2 at 400°C, or by oxidation of d-ethyl n-amyl carbinol with chromates; another synthetic route is reported.
