Ethyl acetate is the organic compound with the formula CH3CH2OC(O)CH3. This colorless liquid has a characteristic, not unpleasant smell like certain glues or nail polish removers, in which it is used. As the ester derived from ethanol and acetic acid, EtOAc, as it is commonly abbreviated, is manufactured on a large scale for use as a solvent.
Ethyl acetate is a moderately polar solvent that has the advantages of being volatile, relatively non-toxic, and non-hygroscopic. It is a weak hydrogen bond acceptor, and only a weak donor. Ethyl acetate can dissolve up to 3% water and has a solubility of 8% in water at room temperature. At elevated temperature its miscibility with water is higher. It is unstable in the presence of strong aqueous bases and acids.
Ethyl acetate is widely employed as a solvent for chemical reactions and for extractions. Similarly, is also present in nail varnishes and nail varnish removers and even for the decaffeination of coffee beans and tea leaves.
Ethyl acetate is also present in confectionery, perfumes, and fruits because it confers a fruity smell, as do most esters.
In this experiment we obtained ester( ethyl acetate) by reaction of acetic acid and alcohol.
