Di Ethanol Amine (DEA)

Diethanolamine (DEA) is an amine compound that appears as a viscous, slightly yellowish liquid with a distinct, milder odor compared to other amines. At room temperature, DEA has higher viscosity than MEA and dissolves well in water, alcohols, and some organic solvents. It also has the ability to absorb moisture from the air, requiring airtight storage to prevent exposure to air and humidity. DEA is denser than water and remains liquid at room temperature.

Industrial Applications:

Absorption of Acidic Gases: One of the primary uses of DEA is in the absorption of acidic gases like CO2 and H2S in petrochemical and refining industries. This property is crucial due to DEA’s ability to chemically bond with these gases, removing them from gas streams.

Chemical Production: DEA is used in the production of various chemicals, including surfactants, emulsifiers, and cleaning agents. These compounds find applications across different industries, including detergent production, personal care, and textiles.

Pharmaceutical and Personal Care Industries: DEA serves as a surfactant and pH adjuster in the production of many personal care products, including creams, lotions, and shampoos.

Paint and Resin Industry: As an intermediate in the production of resins and polymers, DEA is utilized due to its ability to improve the mechanical and chemical properties of the final products.

Due to its unique chemical properties, DEA has extensive and important applications in various industries, playing a vital role in many industrial processes.
