メチルプロピルジケトン 化学特性,用途語,生産方法
説明
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.

天然物の起源
Reported found in fermented soybean, peach, roasted chicken, beer, coffee, shoyu and clam.
使用
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.
