Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.
Molar mass: 278.29 g/mol Appearance white crystals Density: 1.212g/cm^3 Melting point: 154 to 158 °C (309 to 316 °F; 427 to 431 K) ... ethyl acetate and ...
The enzyme acetylacetone dioxygenase cleaves a central carbon-carbon bond of acetylacetone, producing acetate and 2-oxopropanal. The enzyme is iron(II)-dependent, but it has been proven to bind to zinc as well. Acetylacetone degradation has been characterized in the bacterium Acinetobacter johnsonii.

Simple molecules have simple spectra. The spectrum of ethyl chloride consists of a triplet at 1.5 ppm and a quartet at 3.5 ppm in a 3:2 ratio. The spectrum of benzene consists of a single peak at 7.2 ppm due to the diamagnetic ring current. Together with carbon-13 NMR, proton NMR is a powerful tool for molecular structure characterization.
In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3.It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium).
At large scale, ethyl acetoacetate is industrially produced by treatment of diketene with ethanol. [2] The small scale preparation of ethyl acetoacetate is a classic laboratory procedure. [3] It involves Claisen condensation of ethyl acetate. Two moles of ethyl acetate condense to form one mole each of ethyl acetoacetate and ethanol. [4]
