Ethyl acetate and tea leaves are decaffeinated with this solvent. It is also used in paints as an activator or hardener. Ethyl acetate is present in confectionery, perfumes, and fruits. In perfumes, it evaporates quickly, leaving only the scent of the perfume on the skin. In the laboratory, mixtures containing ethyl acetate are commonly used in column chromatography and extractions. Ethyl acetate is rarely selected as a reaction solvent because it is prone to hydrolysis and transesterification. Ethyl acetate is fairly volatile at room temperature and has a boiling point of . Due to these properties, it can be removed from a
Ethyl sulfate 170 °C in a considerable excess of sulfuric acid, the ethyl sulfate breaks down into ethylene and sulfuric acid. The mechanism of the formation of ethyl sulfate, diethyl ether, and ethylene is based on the reaction between ethanol and sulfuric acid, which involves protonation of the ethanolic oxygen to form the oxonium ion. Ethyl sulfate acculates in hair after chronic alcohol consumption and its detection can be used as a biomarker for alcohol consumption. Ethyl sulfate can exist in salt forms, such as sodium ethyl sulfate, potassium ethyl sulfate, and calcium ethyl sulfate. The salt can be formed by adding
