3.Description

Ethyl acetate (systematically, ethyl ethanoate, commonly abbreviated EtOAc or EA) is the organic compound with the formula CH3-COO-CH2-CH3, simplified to C4H8O2. This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, decaffeinating tea and coffee, and cigarettes (see list of additives in cigarettes). Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. 

4.Application  

Ethyl acetate is used primarily as a solvent and diluent, being favored because of its low cost, low toxicity, and agreeable odor. For example, it is commonly used to clean circuit boards and in some nail varnish removers (acetone and acetonitrile are also used). Coffee beans and tea leaves are decaffeinated with this solvent.  It is also used in paints as an activator or hardener.

5.Safety

The LD50 for rats is 5620 mg/kg, indicating low toxicity. Given that the chemical is naturally present in many organisms, there is little risk of toxicity.

Overexposure to ethyl acetate may cause irritation of the eyes, nose, and throat. Severe overexposure may cause weakness, drowsiness, and unconsciousness.

6.Mamufacturing 

In industry, Ethyl acetate is synthesized mainly by ethanol and acetic acid via the classic Fischer esterification reaction. This reaction occurs at room temperature with the yield about 65%, that will more quickly by acid catalysis.

CH3CH2OH + CH3COOH → CH3COOCH2CH3 + H2O

Additionally, Ethyl acetate is also prepared industrially by combining two equivalents of acetaldehyde in the presence of an alkoxide catalyst using the Tishchenko reaction. The yield is about 95%-96%. This method is less cost than others.

2 CH3CHO [Al(OR)3] → CH3COOCH2CH3

What's more, it can also be produced by ethylic acid and ethene via the esterification reaction. The reaction equation is as the following:

CH3COOH + C2H4 → CH3COOC2H5
