Отримання й хімія
Спосіб отримання
The Fischer mixture of ethanol and acetic acid converts to ethyl acetate in about 65% yield at room temperature. Acid catalysts speed the reaction, and removing water shifts the equilibrium toward the ester. Ethyl acetate is also prepared in industry by the Tishchenko reaction, which combines two equivalents of acetaldehyde in the presence of an alkoxide catalyst. A third route is the alkylation of acetic acid with ethylene, using silicotungstic acid as a catalyst. Toluene can be made by reacting benzene with methanol in the presence of a solid acid, which gives toluene and water.

У парфумерії
Ethyl acetate is present in confectionery, perfumes, and fruits and imparts a brief ethereal, fruity, sweet aroma. In perfumes it evaporates quickly, leaving the scent of the perfume on the skin. Ethyl acetate is also used in artificial fruit essences and aroma enhancers, and in artificial flavours for confectionery, ice cream and cakes.
