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 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.
Ethyl group (highlighted blue) as part of a molecule, as the ethyl radical, and in the compounds ethanol, bromoethane, ethyl acetate, and ethyl methyl ether.. In organic chemistry, an ethyl group (abbr. Et) is an alkyl substituent with the formula −CH 2 CH 3, derived from ethane (C 2 H 6).
Ethyl acetate has many advantages and is very widely used. Its fumes are less toxic to humans than those of the other agents, and specimens will remain limp if they are left in an ethyl acetate killing jar for several days and the ethyl acetate is not allowed to entirely evaporate from the specimens.
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]
Phenyl acetate is the ester of phenol and acetic acid.It can be produced by reacting phenol with acetic anhydride or acetyl chloride.. Phenyl acetate can be separated into phenol and an acetate salt, via saponification: heating the phenyl acetate with a strong base, such as sodium hydroxide, will produce phenol and an acetate salt (sodium acetate, if sodium hydroxide were used).
Methyl acetate is occasionally used as a solvent, being weakly polar and lipophilic, but its close relative ethyl acetate is a more common solvent being less toxic and less soluble in water. Methyl acetate has a solubility of 25% in water at room temperature. At elevated temperature its solubility in water is much higher.
Amyl alcohols are alcohols with the formula C 5 H 11 OH. [1] Eight are known. A mixture of amyl alcohols (also called amyl alcohol) can be obtained from fusel alcohol.Amyl alcohol is used as a solvent and in esterification, by which is produced amyl acetate and other products.
