ESTERS THEORY
Hits: 102693

The esters are hydrolyzed in aqueous media, under acid or base catalysis, to yield carboxylic acids and alcohols.

In acidic media, the hydrolysis of esters can be written by the following chemical equation:
 
hidrolisis-acida-esteres
 
The mechanism of acid hydrolysis occurs in the following stages:
 
Stage 1. Protonation of the ester
 
hidrolisis-acida-esteres
 
Stage 2. Nucleophilic addition of water to the carbonyl
 
hidrolisis-acida-esteres
 
Stage 3. Acid-base balance, which transforms the methoxide into a good leaving group (methanol).
 
hidrolisis-acida-esteres
 
Stage 4. Elimination of methanol
