Chemical Properties
Acetoxyacetic acid has the systematic name "3-carbonylbutyric acid". Chemical formula C4H6O4, molecular weight 102.09, crystals can be obtained from ether. Melting point 36-37°C. Miscible with water and ethanol. Miscible with water and ethanol, soluble in ether. It is a strong acid, but unstable, decomposed into acetone and carbon dioxide at about 100℃, with enol form, can show color with ferric chloride, treated with nitrous acid, it will immediately form oxime acetone (CH3COCHNOH) and release carbon dioxide at the same time, while its ester and amide are very stable.
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.
