| Hazard Information | Back Directory | [General Description]
Yellow liquid. Sharp penetrating odor in high concentrations. Sweet, aromatic odor when diluted. | [Reactivity Profile]
2,3-HEXANEDIONE(3848-24-6) is incompatible with strong oxidizing agents and strong bases. | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [Fire Hazard]
This chemical is flammable. | [Description]
2,3-Hexanedione has a powerful, creamy, sweet, and buttery odor
(less than diacetyl) and a buttery, cheese taste. It may be synthesized
from propionyl aldehyde condensed over ethyl acetylacetate;the resulting product is then oxidized (H2O2 and sodium tungstate),
hydrolyzed, and finally decarboxylated to 2,3-hexanedione; from
methyl butyl ketone and ethyl propyl ketone by way of the monoxime;
also from acetoxy mesityl oxide. | [Chemical Properties]

| [Chemical Properties]
yellow liquid | [Occurrence]
Reported found in fermented soybean, peach, roasted chicken, beer, coffee, shoyu and clam. | [Uses]
2,3-Hexanedione was used to evaluate the influence of xanthan concentration on the release of aroma compounds in xanthan-thickened food model systems. | [Uses]
2,3-Hexanedione is used to evaluate the influence of xanthan concentration on the release of aroma compounds in xanthan-thickened food model systems. It reacts with ethylenediamine to yield macrocyclic tetradentate 12-membered nitrogen donor (N4) ligand. | [Definition]
ChEBI: An alpha-diketone that is hexane substituted by oxo groups at positions 2 and 3 respectively. | [Preparation]
From propionyl aldehyde condensed over ethyl acetylacetate; the resulting product is then oxidized (H2O2 and sodium
tungstate), hydrolyzed and finally decarboxylated to 2,3-dexanedione; from methyl butyl ketone and ethyl propyl ketone by way of
the monoxime; also from acetoxy mesityl oxide | [Taste threshold values]
Taste characteristics at 50 ppm: creamy, fruity, toasted brown, caramellic notes. |
