Octane-2,3-dione Chemical Properties,Usage,Production
Chemical Properties
2,3-Octanedione has a “warmed-over” flavor (off-flavor).
Occurrence
Reportedly present in fish, turkey, chicken, beef, lamb, mutton, coffee, tea, peanut, mushroom, prickly pear and lavage leaf.
Uses
The title Octane-2,3-dione is used on a very limited scale in perfume compositions, mainly as a trace component in topnote compositions, }vhere it gives interesting effects in the presence of Civet and Phenylacetic acid, or certain Labdanum products, etc. It is also of good use in Ylang Ylang compositions and in many other flower bases.
Definition
ChEBI: 2,3-Octanedione is an alpha-diketone.

Synthesis
Octane-2,3-dione is prepared in three steps. 1) Preparation of composite catalyst: 5-Methoxytriazole is refluxed with chlorobenzene and acetonitrile to give component 1 (5-methoxy-triphenyl-1,2,4-triazolium salt). 5-Methoxythiazole is refluxed with benzyl chloride and acetonitrile to give component 2 (5-methoxy-2-benzylthiazolium salt). The two are mixed 1:1 to form the composite catalyst. 2) Preparation of Fe3+-Fe2+ redox system: Ferrous sulfate and sulfuric acid react with hydrogen peroxide. 3) Preparation of octane-2,3-dione: Acetaldehyde and hexanal are coupled using the composite catalyst. The crude product is distilled. The distillate is oxidized in the presence of the Fe3+-Fe2+ redox system in a reaction-distillation apparatus. The distillate is collected as the product.
