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.

2-(2-Ethoxyethoxy)ethanol, also known under many trade names, is the organic compound with the formula CH 3 CH 2 OCH 2 CH 2 OCH 2 CH 2 OH. It is a colorless liquid. It is a popular solvent for commercial applications. [1] It is produced by the ethoxylation of ethanol (CH 3 CH 2 OH).
2-Ethoxyethanol, also known by the trademark Ethyl cellosolve, is a solvent used widely in commercial and industrial applications. It is a clear, colorless, nearly odorless liquid that is miscible with water, ethanol, diethyl ether, acetone, and ethyl acetate. [3] 2-Ethoxyethanol is manufactured by the reaction of ethylene oxide with ethanol.
2-Ethoxyethyl acetate has been used to dissolve polyester and short oil alkyd resins. [4] It has also been used in coatings, dyes, insecticides, soaps and cosmetics. [ 5 ] It is also a solvent for nitro-cellulose and is being used for the same applications as ethyl glycol [ 4 ] [ 6 ]
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]
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]
[1] [2] People can be exposed to 2-butoxyethanol acetate in the workplace by breathing it in, swallowing it, skin absorption, or eye contact. Symptoms of exposure include irritation of the eyes, skin, nose, and throat, hemolysis (bursting of red blood cells), hematuria (blood in the urine), central nervous system depression, headache, and ...
