Ethyl acetoacetate Usage And Synthesis
Chemical Properties Colourless, clear liquid
Usage Ethyl acetoacetate (EAA) is used as starting material for the syntheses of alpha-substituted acetoacetic esters and cyclic compounds, e.g. pyrazole, pyrimidine and coumarin derivatives as well as intermediate for vitamins and pharmaceuticals. Product Data Sheet
General Description A colorless liquid with a fruity odor. Flash point 185°F. Boiling point 365°F. May cause adverse health effects if ingested or inhaled. May irritate to skin, eyes and mucous membranes. Used in organic synthesis and in lacquers and paints.
Air & Water Reactions Flammable.
Reactivity Profile Ethyl acetoacetate, a beta-keto ester, is more reactive than many esters. Undergoes an exothermic cleavage reaction in the presence of concentrated base. Reacts with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Mixing with 2,2,2-tris(bromomethyl)ethanol and zinc led to an explosion [US Patent 3 578 619, Crotonaldehyde may rapidly polymerize with Ethyl acetoacetate (Soriano, D.S. et al. 1988. Journal of Chemical Education 65:637.).1971].
Health Hazard Liquid may cause mild irritation of eyes.
