3-Octanone is a chemical compound from the group of dialkyl ketones .
Occurrence
3-Octanone occurs naturally in various plants such as lavender , rosemary, and nectarines . The compound is also produced by fungi and is therefore classified as a secondary indicator in the room air for mold infestation . Certain ants such as the red garden ant ( Myrmica rubra ) also synthesize 3-octanone.
Extraction and presentation
3-Octanone can be obtained by heating propionic acid and caproic acid over thorium (IV) oxide or by oxidizing ethyl amyl ketone carbinol .
properties
3-Octanone is a slightly volatile, flammable, colorless liquid with a mild fruity odor that is sparingly soluble in water. It decomposes when heated, producing, among other things, carbon monoxide and carbon dioxide .
use
3-octanone is used as a flavoring agent.
safety instructions
The vapors of 3-octanone can form an explosive mixture with air ( flash point 53 ° C, ignition temperature 330 ° C).
