preparation of ethyl acetate
Ethyl acetate - Wikipedia
Ethyl acetate was first synthesized by the Count de Lauraguais in 1759 by distilling a mixture of ethanol and acetic acid. In 2004, an estimated 1.3 million tonnes were produced worldwide. The coined annual production in 1985 of Japan, North America, and Europe was about 400,000 tonnes. The global ethyl acetate market was valued at $3.3 billion in 2018.

Ethyl Acetate Formula with Solved Examples
The Lewis basicity of ethyl acetate is only moderate. With I2, phenol, and bis (hexafluoroacetylacetonate)copper, it forms 1:1 adducts (II). When ethyl acetate is hydrolyzed, acetic acid and ethanol are produced. Bases speed up the hydrolysis, which is subject to the above-mentioned Fischer equilibrium.
