production

Ethyl acetate is produced industrially by Fischer esterification, although there are alternative routes such as the Tishchenko reaction. In Fischer esterification, ethanol and acetic acid are reacted at room temperature.

General features

Ethyl acetate is an organic compound formed by replacing the hydroxy group with ethoxy. It is systematically named ethyl ethanoate and abbreviated as ‘EtoAc, ETAC or EA’. It has an odor similar to pear juice. It is one of the substances that make up the flavor mentioned in old wines. Its solubility in water is low, it is generally soluble in organic solvents such as alcohol ketone ether. Ethyl acetate, the ester of ethanol and acetic acid, is a powerful solvent widely used in industry and is very useful for some applications thanks to its high volatility.

Usage areas

Ethyl acetate is generally used as a solvent and diluent. It is preferred because of its low toxicity, affordable cost and pleasant smell. It is used very often in perfumes and when used for this purpose, it leaves the scent on the desired area and evaporates quickly. It can be used with acetone as a nail polish remover. It acts as a hardener in paints. Ethyl acetate is also very suitable for dissolving caffeine and is used to remove caffeine from products containing caffeine, such as coffee and tea.

In addition, mixtures containing ethyl acetate are widely used in column chromatography and extractions in the laboratory. In the field of entomology, it is used as a suffocator in insect collection and examination. If there is enough ethyl acetate in a closed container where insects are collected, insects can be killed without harming their appearance. Ethyl acetate also keeps their skin soft enough if insects are to be used for collection.

Safety Precautions and Toxicity

Ethyl acetate shows low toxicity and the LD50 value is up to 11.3 g/kg in rats. It occurs naturally in many organisms and fruits. Overexposure may cause irritation to eyes, nose and throat. At higher rates, it can cause weakness, drowsiness and loss of consciousness. However, ethyl acetate is highly flammable and its vapors can form explosive mixtures with air. Therefore, it should be kept away from fire and heat, and should be kept in tightly closed containers.
