Technical Document

What is Ethyl Acetate?

Ethyl acetate is a clear colorless liquid with a fruity odor. It is found in alcoholic beverages. It is also found in cereal crops, radishes, fruit juices, beer, wine, spirits, etc. It is produced by Anthemis nobilis (Roman chamomile) and the Rubus species. Ethyl Acetate is an organic ester compound with a molecular formula of CH3COOCH2CH3, commonly abbreviated as EtOAc or EA. It is highly miscible with all common organic solvents (alcohols, ketones, glycols, esters), which make it a common solvent for cleaning, paint removal, and coatings. Due to its agreeable aroma and low cost, ethyl acetate is commonly used and manufactured on a large scale worldwide. Ethyl acetate density is 902 / kg/m³.

Manufacturing Process

Ethyl acetate is synthesized in the industry mainly via the Fischer esterification reaction with ethanol and acetic acid. This mixture converts to the ester in about 65% yield at room temperature:

CH3CH2OH + CH3COOH → CH3COOCH2CH3 + H2O.

The reaction can be accelerated by acid catalysis and the equilibrium can be shifted to the right by the removal of water. It can also be prepared using the Tishchenko reaction by combining two equivalents of acetaldehyde in the presence of an alkoxide catalyst:

2CH3CHO → CH3COOCH2CH3
