Dietyleenitriamiini

Dietyleenitriamiini, often abbreviated as DETA, is an organic compound with the chemical formula C4H13N3. It is a colorless liquid with an ammonia-like odor. DETA is a member of the ethylenediamine family of compounds and is characterized by its three nitrogen atoms and a flexible hydrocarbon chain. It is soluble in water and many organic solvents.

Industrially, DETA is produced through the reaction of ethylenediamine with ethylene oxide or ethylene dichloride. Its chemical structure, featuring multiple amine groups, makes it highly reactive and useful in various applications.

One of the primary uses of DETA is as a curing agent for epoxy resins. It reacts with the epoxide groups in the resin, forming a cross-linked polymer network that results in a hard, durable material. This property makes it valuable in coatings, adhesives, and composite materials. DETA also finds application as a chelating agent, capable of binding to metal ions, which is utilized in water treatment and metal cleaning processes. Furthermore, it serves as an intermediate in the synthesis of other chemicals, including surfactants and agricultural chemicals. Its handling requires care due to its corrosive nature.
