What is Ethyl Acetate?
Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula 4H8O2, simplified to CH3-COO-CH2-CH3.
This colorless liquid has a characteristic sweet odor (similar to pear drops) and is used in adhesives, nail polish removers, and the decaffeination of tea and coffee. Ethyl acetate is the ester of ethanol and acetic acid; It is produced on a large scale for use as a solvent.
How is Ethyl Acetate produced?
Ethyl acetate was first synthesized by Count de Lauraguais in 1759 by distillation of a mixture of ethanol and acetic acid.
Etil asetat, endüstride esas olarak etanol ve asetik asidin klasik Fischer esterleştirme reaksiyonu yoluyla sentezlenir. Bu karışım, oda sıcaklığında yaklaşık %65 verimle estere dönüşür. Reaksiyon asit katalizi ile hızlandırılabilir ve su uzaklaştırılarak denge sağa kaydırılabilir.
It can also be prepared industrially using the Tishchenko reaction by combining two equivalents of acetaldehyde in the presence of an alkoxide catalyst.
Silicotungstic acid is used to produce ethyl acetate by alkylation of acetic acid with ethylene:

In which sectors is Ethyl Acetate used?
- Solvent and diluent
- cosmetics industry
- food industry
- paint industry
- lab uses
What are the usage areas (processes) of Ethyl Acetate?
- Ethyl acetate is primarily used as a preferred solvent and diluent due to its low cost, low toxicity and pleasant odour.
- Commonly used to clean circuit boards.
- Used in some nail polish removers (acetone is also used).
- Coffee beans and tea leaves are decaffeinated with this solvent (when supercritical CO2 extraction is not possible).
- It is also used as an activator or hardener in paints.
- Ethyl acetate is found in confectionery, perfumes, and fruit. It evaporates quickly in perfumes, leaving only the scent of the perfume on the skin.
- In the laboratory, mixtures containing ethyl acetate are widely used in column chromatography and extractions. Ethyl acetate is rarely chosen as a reaction solvent as it is prone to hydrolysis, transesterification, and condensations.
- Ethyl acetate is the most common ester in wine, the most common volatile organic acid - acetic acid and the product of ethyl alcohol produced during fermentation. The aroma of ethyl acetate is most vibrant in young wines and contributes to the overall sense of "fruitiness" in the wine. Sensitivity varies with most people having a detection threshold of around 120 mg/L. An excessive amount of ethyl acetate is considered a wine defect.
