Ethyl acetate is easily hydrolyzed, and when water is present at room temperature, it is gradually hydrolyzed to acetic acid and ethanol. Adding a small amount of acid or base can promote the hydrolysis reaction. The biggest difference between alkaline hydrolysis and acid hydrolysis of ethyl acetate is that alkaline hydrolysis is irreversible, that is, reversible process and irreversible process in the reaction mechanism. Acetic acid reacts reversibly with ethanol to form ethyl acetate. Old wine is good to drink, because a small amount of acetic acid in the wine reacts with ethanol to produce a fruity aroma of ethyl acetate.
