Fischer Esterification (Ethanol + Acetic Acid)

CH3COOH + C2H5OH ⇌ CH3COOC2H5 + H2O

概要

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.
