Ethyl Acetate colorless
liquid has a characteristic sweet smell (similar to pear drops) and is used in
glues, nail polish removers, and in the decaffeination process of tea and
coffee. Ethyl acetate is the ester of ethanol and acetic acid; it is
manufactured on a large scale for use as a solvent.
It is used primarily as a solvent and diluent, being favored because of its low cost, low toxicity, and
agreeable odor. For example, it is commonly used to clean circuit boards and
in some nail varnish removers (acetone and acetonitrile are also used). Coffee beans 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 trans-esterification It is the most common ester in wine, being the product of the most common volatile organic acid â€“ acetic acid, and the ethyl
alcohol generated during the fermentation.
