What is the boiling point of diethanolamine (CAS 111-42-2)?

diethanolamine boiling point

In the field of chemistry, diethanolamine is an extremely important organic compound, playing a crucial role in numerous industrial and everyday applications. The boiling point of diethanolamine, as an important physical property, is indispensable for understanding its characteristics and its applications in practical production.

The boiling point of diethanolamine is 268.8℃. This relatively high boiling point reflects the strong intermolecular forces of diethanolamine. Due to the presence of hydroxyl and amino groups in the molecule, these polar groups can form hydrogen bonds, making the intermolecular bonds more compact. Higher energy is required to transform the molecule from a liquid to a gaseous state, thus resulting in a high boiling point.

diethanolamine (CAS 111-42-2) Uses

• As an emulsifier: DEA can mix water and oil together, therefore it is widely used in the coatings, plastics, and ink industries.
• Improving product flowability: DEA acts as a delayed emulsifier and wetting agent, improving the flowability and gloss of products.
• Adjusting pH: Diethanolamine is an organic base that can be used to adjust the pH of solutions, commonly used in cosmetics and personal care products.
• Inhibiting bacterial and fungal growth: Diethanolamine has bactericidal and disinfectant properties, preventing the growth and reproduction of microorganisms, and is therefore commonly used in soaps, detergents, pesticides, and other related products.

How is diethanolamine (CAS 111-42-2) stored safely?

To ensure the safe use of diethanolamine (CAS 111-42-2), the following recommendations are provided:

Ethanolamine should be stored in a cool, dry, well-ventilated place, away from fire and heat sources, and away from direct sunlight.

During handling, personal protective equipment such as respirators, chemical protective goggles, and protective clothing should be worn to prevent direct skin contact or vapor inhalation.

While using ethanolamine, monitor your physical condition. If any discomfort occurs, seek medical attention immediately.
