2,3-HEXANEDIONE C화학적 특성, 용도, 생산
개요
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.화학적 성질

Reported found in fermented soybean, peach, roasted chicken, beer, coffee, shoyu and clam.용도
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.제조 방법
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 oxide정의
ChEBI: An alpha-diketone that is hexane substituted by oxo groups at positions 2 and 3 respectively.일반 설명
