Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. [9] For example, it is commonly used to clean circuit boards and in some nail varnish removers (acetone is also used). In chemistry, an ethyl group is an alkyl substituent derived from ethane (C2H6). Because it is not hygroscopic, ethyl acetate also keeps the insect soft enough to allow proper mounting suitable for a collection. [11] Ethyl acetate is rarely selected as a reaction solvent because it is prone to hydrolysis, transesterification, and condensations. The global ethyl acetate market was valued at $3.3 billion in 2018.[7].

This compound is not available in nature in a huge amount but it is available in wines or other alcoholic beverages. It is also prepared in industry using the Tishchenko reaction, by combining two equivalents of acetaldehyde in the presence of an alkoxide catalyst: Silicotungstic acid is used to manufacture ethyl acetate by the alkylation of acetic acid by ethylene:[8]. IDENTIFICATION: Ethyl phenyl acetate is a colorless liquid.
