Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2. This colorless liquid has a characteristic sweet smell (similar to pear drops ) and is used in glues , nail polish removers , and the decaffeination process of tea and ...
A rotary evaporator [1] (rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was evaporated ...
The Swedish ethyl acetate method ( SweEt) is a method for chemical analysis of pesticide residues in food using ethyl acetate as an extraction medium followed by analysis with liquid chromatography - tandem mass spectrometry (LC-MS/MS) and gas chromatography -tandem mass spectrometry (GC-MS/MS). It was developed by the Swedish National Food ...
The conversion of methyl acetate back into its components, by an acid, is a first-order reaction with respect to the ester. The reaction of methyl acetate and a base, for example sodium hydroxide, is a second-order reaction with respect to both reactants. Methyl acetate is a Lewis base that forms 1:1 adducts with a variety of Lewis acids.

Fischer esterification or Fischer–Speier esterification is a special type of esterification by refluxing a carboxylic acid and an alcohol in the presence of an acid catalyst. The reaction was first described by Emil Fischer and Arthur Speier in 1895. [1] Most carboxylic acids are suitable for the reaction, but the alcohol should generally be ...
2-Ethoxyethanol, also known by the trademark Ethyl cellosolve, is a solvent used widely in commercial and industrial applications. It is a clear, colorless, nearly odorless liquid that is miscible with water, ethanol, diethyl ether, acetone, and ethyl acetate. [3] 2-Ethoxyethanol is manufactured by the reaction of ethylene oxide with ethanol.
Rectified spirit, also known as neutral spirits, rectified alcohol or ethyl alcohol of agricultural origin, [ 1 ] is highly concentrated ethanol that has been purified by means of repeated distillation in a process called rectification. In some countries, denatured alcohol or denatured rectified spirit may commonly be available as "rectified ...
