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 cyanoacetate This reactivity is similar to that of esters of malonic acid. As an example of reactivity at the nitrile, diethyl malonate is obtained from cyanoacetic acid ethyl ester by reaction with ethanol in the presence of strong acids. Heating in the presence of sodium ethoxide forms the dimeric 3-amino-2-cyano-2-pentendiaciddiethylester. Due to its functionality cyanoacetate reacts: Ethyl cyanoacetate is a building block for the synthesis of heterocycles which are used for example as drugs: Also many other functional heterocycles are in good yields accessible from ethyl cyanoacetate, such as 3-substituted coumarin derivatives. Non-cyclic products from this starting material include: Ethyl cyanoacetate
