Study Notes
Esterification
- Esterification is a reaction between a carboxylic acid and an alcohol, catalyzed by a strong mineral acid (e.g., sulfuric acid or hydrochloric acid).
- The reaction produces an ester and water.
Mechanism of Esterification
- The carboxylic acid and alcohol react to form an ester and water.
- The reaction involves the elimination of water, with the hydrogen from the alcohol and the H from the carboxylic acid combining to form water.
Acetic Acid and Ethanol Reaction
- Acetic acid and ethanol react to form ethyl acetate and water.
- The reaction involves the elimination of water, with the hydrogen from ethanol and the H from acetic acid combining to form water.
Acetic Acid and Isobutanol Reaction
- Acetic acid and isobutanol react to form isobutyl acetate and water.
- The reaction involves the elimination of water, with the hydrogen from isobutanol and the H from acetic acid combining to form water.
Intramolecular Esterification
- Intramolecular esterification occurs when a carboxylic acid and an alcohol are part of the same molecule.
- The reaction forms a cyclic ester (lactone) and water.
4-Hydroxybutanoic Acid and Methanol Reaction
- 4-Hydroxybutanoic acid and methanol react to form a cyclic ester (lactone) and water.
- The reaction involves the elimination of water, with the hydrogen from methanol and the H from 4-hydroxybutanoic acid combining to form water.
Fischer Esterification
- Fischer esterification is a type of esterification reaction that occurs between a carboxylic acid and an alcohol, catalyzed by a strong mineral acid.
- The reaction produces an ester and water.
Characteristics of Esters
- Esters have a sweet, fruity smell.
- Esters are commonly used in perfumes, flavorings, and fragrances.
- Esters have a lower boiling point than carboxylic acids and alcohols.
