Ethyl Acetate Formula

Ethyl acetate formula is given here along with its structure. Ethyl acetate, also known as ethyl ethanoate is one organic compound and is mainly used as a solvent in different reactions. Ethyl acetate if obtained from the direct esterification of ethyl alcohol with acetic acid, a process which involves mixing acetic acid with an excess of ethyl alcohol and adding a small amount of sulfuric acid.

The formula for ethyl acetate is CH3COOCH2CH3. 

Commercially, ethyl acetate is made from 10% acetic acid “quick vinegar” process and 50% alcohol “high wines” by a distillation process. A ternary mixture of ethyl acetate, water and ethyl alcohol distils first. Ethyl acetate is a colourless and sweet-smelling ester of acetic acid and ethanol. The chemical and structural formula of ethyl ethanoate is mentioned below.

Ethyl Acetate Formula

Ethyl ethanoate is generally abbreviated as EtOAc, EA, or ETAC. It has a molar mass of 88.106 g/mole. The carbonyl group carbon has an sp2 hybridization and the other part of the molecule has a tetrahedral geometry. The chemical formula for ethyl acetate and its structural formula are given below.

Ethyl Acetate Uses

  • Used as an indirect food additive in certain packaging materials.
  • Used as an oxygenated solvent widely used in the inks, pharmaceuticals and fragrance sectors.
  • Used as flavouring agents and preservatives in the food industry.
  • Used as a good solvent for nitrocellulose, fats, varnishes, lacquers inks and aeroplane dopes, it is used in the production of smokeless powder, artificial leather, photographic films and plates and artificial silk.
  • Used as a cleaning agent in the textile industry.

Health Hazard

  • Acute toxicity was reported while the inhalation in rats as 5.6g/kg after 8hrs.
  • It is tested in petroleum produced no irritation after 48hr closed patch test in 25 human subjects.
  • It is tested at a concentration of 10% in petroleum and produced no sensitization reactions.
  • It is hydrolysed to ethyl alcohol which is then partly excreted in the expired air and urine.
