| Ethyl acetoacetate Usage And Synthesis |
| Chemical Properties | Colourless, clear liquid |
| Uses | 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 |
| Definition | This compound is a tautomer at room temperature consisting of about 93% keto form and 7% enol form. |
| 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]. |
| Hazard | Toxic by ingestion and inhalation; irritant to skin and eyes. |
| Health Hazard | Liquid may cause mild irritation of eyes. |
| Safety Profile | eye irritant. Combustible liquid when exposed to heat or flame; can react with oxidzing materials. Explosive reaction when heated with Zn + tribromoneopentyl alcohol or 2,2,2- tris(bromomethy1)ethanol. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS. |
| Purification Methods | Shake the ester with small amounts of saturated aqueous NaHCO3 (until no further effervescence), then with water. Dry it with MgSO4 or CaCl2 and distil it under reduced pressure. [Beilstein 3 IV 1528.] |
