Diethylethanolamine (CAS 100-37-8) is a multi-functional amino alcohol with a tertiary amine structure, supplied as a colorless liquid with a characteristic amine odor, and it is used as a volatile neutralizing amine in steam boiler systems, as a pH-adjusting additive in water-borne coatings, and as an intermediate in chemical synthesis. It is a colorless liquid with a characteristic amine odor, offering excellent neutralizing and anti-corrosive properties.
In steam boiler systems, it acts as a Technical Grade volatile neutralizing amine, preventing carbonic acid corrosion in condensate lines. Its ability to partition effectively between steam and water ensures comprehensive protection for the entire heating circuit.
Furthermore, DEEA serves as a vital chemical intermediate in the production of pharmaceuticals, emulsifiers, and textile auxiliaries. Its tertiary amine structure makes it an efficient catalyst in the manufacture of polyurethane foams and resins.
