2,3-HEXANEDIONE Structural

What is 2,3-HEXANEDIONE?

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

yellow liquid

2,3-Hexanedione has a powerful, creamy, sweet and buttery odor (less than diacetyl) and a buttery cheese taste.

Occurrence

Reported found in fermented soybean, peach, roasted chicken, beer, coffee, shoyu and clam.

The Uses of 2,3-HEXANEDIONE

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.
