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.
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. [13] CH 3 C(O)CH 2 C(O)CH 3 + O 2 → CH 3 ...
The dianion of ethyl acetoacetate is also a useful building block, except that the electrophile adds to the terminal carbon. The strategy can be depicted in the following simplified form: [6] CH 3 C(O)CHNaCO 2 C 2 H 5 + BuLi → LiCH 2 C(O)CHNaCO 2 C 2 H 5 + BuH (Bu = butyl) Reduction of ethyl acetoacetate gives ethyl 3-hydroxybutyrate.

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).
In the diluted form with 4% ethyl acetate and ethanol the CAS number is 69382-62-3. [3] Toxicity may be due to metabolism products hydrogen sulfide and acetaldehyde, however as used it has a margin of safety of over 10,000,000. [2]
Ph 3 PO is structurally related to POCl 3. [2] As established by X-ray crystallography, the geometry around P is tetrahedral, and the P-O distance is 1.48 Å. [3] Other modifications of Ph 3 PO have been found: For example, a monoclinic form crystalizes in the space group P2 1 /c with Z = 4 and a = 15.066(1) Å, b = 9.037(2) Å, c = 11.296(3) Å, and β = 98.47(1)°.The orthorhombic ...
Ethyl cyanoacetate is an organic compound that contains a carboxylate ester and a nitrile. It is a colourless [ 1 ] liquid with a pleasant odor. This material is useful as a starting material for synthesis due to its variety of functional groups and chemical reactivity.
