Fischer Esterification (Ethanol + Acetic Acid)

CH₃COOH + C₂H₅OH ⇌ CH₃COOC₂H₅ + H₂O

Overview

Acetic acid reacts with ethanol in the presence of an acid catalyst to form ethyl acetate and water. This reversible condensation reaction is the classic Fischer esterification. The equilibrium is driven to the right by using excess alcohol or removing water. Ethyl acetate has a characteristic fruity smell.

Everyday Example

The fruity smell of nail polish remover is ethyl acetate produced by this esterification reaction. Many fruit flavors are esters made similarly.

Industrial Importance

Ethyl acetate is the world's most widely used organic solvent, produced at over 3 million tonnes annually for coatings, adhesives, and pharmaceutical extractions.
