| Hazard Information | Back Directory | 【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. | 【Reactivity Profile】
ETHYL ACETOACETATE(141-97-9), 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(141-97-9) (Soriano, D.S. et al. 1988. Journal of Chemical Education 65:637.).1971]. | 【Air & Water Reactions】
Flammable. | 【Health Hazard】
Liquid may cause mild irritation of eyes. |
