개요
2, 5-hexadione (2,5HD) is a flammable, transparent colorless to amber water-soluble liquid that is a multifunctional platform chemical, a major metabolite of n-hexane, and a key intermediate for the production of high energy density aviation fuels from biomass resources. It has a sweet aromatic smell and neurotoxic effects. It can be used as a high energy density fuel additive of platform chemicals, and can induce ovarian granulosa cell cycle arrest to establish ovarian injury model. It can also be used for biological monitoring of 2, 5-hexanedione exposure to n-hexane[1-2].화학적 성질
colourless to pale yellow liquid용도
It is the metabolite implicated in n-hexane neurotoxicity.주요 응용
2,5-Hexanedione is a neurotoxic metabolite of n-hexanes and methyl n-butyl ketone. It is also used as the starting material for diels-alder cycloaddition reactions, such as a reactions with amines to form 2,5-dimethylpyrroles.제조 방법
20 g of diethyl 2,3-diacetylbutanedioate are mechanically shaken for several days with 250 ml (excess) of 5% aqueous sodium hydroxide, and until no diethyl 2,3-diacetylbutanedioate separates on acidification of a sample with dilute hydrochloric acid. The solution is then saturated with potassium carbonate and extracted with ether, the extract is washed with brine to remove alcohol, dried over calcium chloride, and distilled, the fraction 192-198° C being retained. You can get 2,5-Hexanedione with a yield of 70%. Colourless liquid; agreeable odour; miscible with water, alcohol and ether; m.p. 9° C; b.p. 194° C; d=0.973 g/ml at 20° C.
정의
ChEBI: A diketone that is hexane substituted by oxo groups at positions 2 and 5. It is a toxic metabolite of hexane and of 2-hexanone
일반 설명
Clear colorless to amber liquid with a sweet aromatic odor.공기와 물의 반응
Highly flammable. Water soluble.반응 프로필
Acetonylacetone is incompatible with oxidizing agents. Acetonylacetone is also incompatible with strong bases and strong reducing agents.화재위험
Acetonylacetone is combustible.Purification Methods
Purify it by dissolving in Et2O, stiring with K2CO3 (a quarter of the weight of dione), filtering, drying over anhydrous Na2SO4 (not CaCl2), filtering again, evaporating the filtrate and distilling it in a vacuum. It is then redistilled through a 30cm Vigreux column (p 11, oil bath temperature 150o). It is miscible with H2O and EtOH. The dioxime has m 137o (plates from *C6H6), the mono-oxime has b 130o/11mm, and the 2,4-dinitrophenylhydrazone has m 210-212o (red needles from EtOH). It forms complexes with many metals.
