etüülatsetaat

Etüülatsetaat, also known as ethyl acetate, is an organic compound with the chemical formula CH3COOCH2CH3. It is an ester formed from ethanol and acetic acid. At room temperature, it is a colorless liquid with a characteristic sweet, fruity odor, reminiscent of pear drops. Its low cost, low toxicity, and desirable evaporation rate make it a common choice for various industrial and domestic applications.

Etüülatsetaat is widely used as a solvent. It is effective at dissolving many resins, nitrocellulose, lacquers, paints, and coatings. This makes it a popular ingredient in nail polish removers, glues, and printing inks. It is also used in the decaffeination process of coffee and tea, and in the extraction of pharmaceuticals. Due to its pleasant aroma, it finds application in perfumes and flavorings, though its use in food is regulated.

The production of etüülatsetaat typically involves the Fischer esterification of ethanol and acetic acid in the presence of an acid catalyst. It can also be produced through the Tishchenko reaction, where acetaldehyde undergoes a disproportionation reaction. Etüülatsetaat is flammable and its vapors can form explosive mixtures with air, so appropriate safety precautions are necessary when handling it. It is soluble in most organic solvents and moderately soluble in water.
