| | 2,3-HEXANEDIONE Usage And Synthesis |
| 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 | 2,3-Hexanedione has a powerful, creamy, sweet and buttery odor (less than diacetyl) and a buttery cheese taste.
| | Chemical Properties | yellow liquid | | Occurrence | Reported found in fermented soybean, peach, roasted chicken, beer, coffee, shoyu and clam. | | 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. | | 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. | | 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. | | General Description | Yellow liquid. Sharp penetrating odor in high concentrations. Sweet, aromatic odor when diluted. | | Air & Water Reactions | Highly flammable. Insoluble in water. | | Reactivity Profile | 2,3-HEXANEDIONE is incompatible with strong oxidizing agents and strong bases. | | Fire Hazard | 2,3-HEXANEDIONE is flammable. |
