| Hazard Information | Back Directory | [Chemical Properties]
Acetoxyacetic acid has the systematic name "3-oxobutyric acid." Its chemical formula is C??H??O??. Its molecular weight is 102.09. It can be obtained as crystals from diethyl ether. Its melting point is 36-37°C. It is miscible with water and ethanol and soluble in diethyl ether. It is a strong but unstable acid, decomposing into acetone and carbon dioxide at approximately 100°C. It has an enol form that reacts with ferric chloride to produce color. Treatment with nitrous acid immediately forms oxime acetone (CH??COCHNOH) with the release of carbon dioxide. Its esters and amides are extremely stable. | [Uses]
Acetoxyacetic acid was used in preparation of tert-butyl glycolate. | [General Description]
Acetoxyacetic acid is kinetically stable degradation product of oxidative degradation of 1,3-dialkylimidazolium ionic liquids in hydrogen peroxide/aceticacid aqueous medium assisted by ultrasonic chemical irradiation. It is an intermediate formed during reactions of manganic acetate in glacial acetic acid with benzene (100°C), chlorobenzene, or toluene. |
