What is the Difference Between Triethylamine and Triethanolamine?

Triethylamine and triethanolamine are organic compounds containing nitrogen atoms at the center of their molecules. The key difference between the two lies in their chemical structures and properties:

• Triethylamine: This is an amine compound with the chemical formula N(CH2CH3)3, commonly abbreviated as Et3N. It has a central nitrogen atom bonded to three ethyl groups. Triethylamine is a colorless volatile liquid with a strong fishy odor reminiscent of ammonia. It is mainly used in the production of quaternary ammonium compounds for textile, as a catalyst and acid neutralizer for condensation reactions, and in the production of pesticides and other chemicals.
• Triethanolamine: Also known as TEOA, this is an organic compound with the chemical formula N(CH2CH2OH)3. It is a colorless, viscous liquid that is both a tertiary amine and a triol. Triethanolamine is used primarily in making surfactants, such as emulsifiers, and is a common ingredient in formulations used for both industrial and consumer products. It is found in products like sunscreen lotions, liquid laundry detergents, dishwashing liquids, general cleaners, hand sanitizers, polishes, metalworking fluids, paints, shaving cream, and printing inks.

In summary, triethylamine is an amine compound with a central nitrogen atom bonded to three ethyl groups, while triethanolamine is an alcoholic compound with a central nitrogen atom bonded to three ethanol groups.
