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.
Acetaldehyde was first observed by the Swedish pharmacist/chemist Carl Wilhelm Scheele (1774); [16] it was then investigated by the French chemists Antoine François, comte de Fourcroy and Louis Nicolas Vauquelin (1800), [17] and the German chemists Johann Wolfgang Döbereiner (1821, 1822, 1832) [18] and Justus von Liebig (1835).
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).

The Tishchenko reaction of acetaldehyde gives the commercially important solvent ethyl acetate.The reaction is catalyzed by aluminium alkoxides. [5]The Tishchenko reaction is used to obtain isobutyl isobutyrate, a specialty solvent.
For example, the reaction of acetic anhydride with ethanol yields ethyl acetate: (CH 3 CO) 2 O + CH 3 CH 2 OH → CH 3 CO 2 CH 2 CH 3 + CH 3 COOH. Often a base such as pyridine is added to function as catalyst. In specialized applications, Lewis acidic scandium salts have also proven effective catalysts. [12]
Acetoacetic acid (IUPAC name: 3-oxobutanoic acid, also known as acetonecarboxylic acid or diacetic acid) is the organic compound with the formula CH 3 COCH 2 COOH. It is the simplest beta-keto acid, and like other members of this class, it is unstable.
Chemists often represent acetate as OAc − or, less commonly, AcO −. Thus, HOAc is the symbol for acetic acid, NaOAc for sodium acetate, and EtOAc for ethyl acetate [1] (as Ac is common symbol for acetyl group CH 3 CO [2] [3]).The pseudoelement symbol "Ac" is also sometimes encountered in chemical formulas as indicating the entire acetate ...
