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].

DescriptionThe organic compound ethyl acetoacetate (EAA) is the ethyl ester of acetoacetic acid. It is mainly used as a chemical intermediate in the production of a wide variety of compounds, such as amino acids, analgesics, antibiotics, antimalarial agents, antipyrine and amino pyrine, and vitamin B1; as well as the manufacture of dyes, inks, lacquers, perfumes, plastics, and yellow paint pigments. Alone, it is used as a flavoring for food.
OccurrenceNaturally occurring in strawberry, coffee, sherry, passion fruit juice (yellow), babaco fruit (Carica pentagona Heilborn) and bread.
UsesEthyl acetoacetate is used as an intermediate in organic synthesis and as a co-promoter for unsaturated polyester resins. It is widely used in the production of dyes, inks, perfumes, plastics and flavoring agents. It is an important starting material for the syntheses of alpha-substituted acetoacetic esters and cyclic compounds like pyrazole, pyrimidine and coumarin derivatives. It acts as an intermediate in the synthesis of vitamins and pharmaceuticals. It finds application as a formaldehyde scavenger.
General DescriptionA 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.
PreparationEthyl acetoacetate is produced industrially by treatment of diketene with ethanol. The preparation of ethyl acetoacetate is a classic laboratory procedure . It is prepared via the Claisen condensation of ethyl acetate. Two moles of ethyl acetate condense to form one mole each of ethyl acetoacetate and ethanol.
DefinitionChEBI: Ethyl acetoacetate is an ethyl ester resulting from the formal condensation of the carboxy group of acetoacetic acid with ethanol. It has a role as a flavouring agent, an antibacterial agent and a plant metabolite. It is functionally related to an acetoacetic acid.
