3.Description
Ethyl acetate (systematically, ethyl ethanoate, commonly
abbreviated EtOAc or EA) is the organic compound with the formula
CH*-COO-CH*-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 LD*0 for rats is ***0 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 *5%, 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
*5%**6%. 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
