No.CAS:111-42-2

Diethanolamine (DEA) is an important organic amine and diol, possessing both secondary amine and alcohol functionalities. It is primarily used as an acidic gas (e.g., carbon dioxide, hydrogen sulfide) absorbent, a raw material for nonionic surfactants, a corrosion inhibitor, and an important intermediate for synthesizing herbicides (e.g., glyphosate), personal care products, and polyurethane cross-linking agents.

Description

Diethanolamine (abbreviated as DEA, CAS No.: 111-42-2) is a key member of the ethanolamine series (monoethanolamine MEA, diethanolamine DEA, triethanolamine TEA), produced by the reaction of ethylene oxide with aqueous ammonia followed by distillation and separation. Its molecular structure contains one secondary amino group and two hydroxyethyl groups, imparting excellent alkalinity, water solubility, and reactivity with organic acids.
In gas purification, its aqueous solutions are widely used in natural gas processing, synthetic ammonia, and refining industries to absorb and remove acidic gases such as carbon dioxide (CO₂), hydrogen sulfide (H₂S), and sulfur dioxide (SO₂). It is a key component in decarbonization processes like the "Benfield" solution.
In surfactants and personal care, the alkanolamides (e.g., 6501, 6502) formed by the reaction of DEA with coconut fatty acid are highly effective nonionic surfactants and foam stabilizers, extensively used in shampoos, body washes, and light-duty detergents as thickeners and foam modifiers. It is also used as a softener and lubricant in the textile and leather industries.
As an industrial additive, DEA is an important corrosion inhibitor used in boiler water treatment, metalworking fluids, automotive antifreeze, and various lubricants. Additionally, it serves as an acid acceptor and plasticizer in adhesives.
In chemical synthesis, DEA is a critical intermediate for the production of the herbicide glyphosate. Dehydration cyclization with sulfuric acid yields morpholine (1,4-oxazacyclohexane), an important pharmaceutical and chemical intermediate. In the polyurethane industry, DEA is used as a cross-linking agent in the production of high-resilience foam.
Our product, manufactured in Shandong, China, is produced using advanced processes with a purity of ≥99.5%, low levels of homolog impurities (MEA, TEA), and stable quality. This product is corrosive and hygroscopic, and can cause irritation to eyes, skin, and the respiratory tract. Protective equipment must be worn and forced draft ventilation ensured during handling. For long-term storage, ensure tight sealing to prevent moisture absorption. Note that it may solidify below 28°C and must be returned to a liquid state before use.
