Acetoacetic Acid Chemical Properties,Usage,Production
Uses
In organic syntheses.
Definition
ChEBI: A 3-oxo monocarboxylic acid that is butyric acid bearing a 3-oxo substituent.
Reactivity Profile
Acetone enolate equivalent in alkylations, carbonyl additions, conjugate additions, and diazonium ion coupling reactions[4-7].
Synthesis
Traditionally prepared by base hydrolysis of Ethyl Acetoacetate. A high yield synthesis by acid hydrolysis of Diketene is also reported[1-3].
storage
Handling, Storage, and Precautions: acetoacetic acid is extremely hygroscopic but can be stored under vacuum in a freezer for several weeks with little change. It decomposes rapidly to acetone and carbon dioxide when heated above the melting point. Use in a fume hood.
