Diethylenetriamine (CAS 111-40-0), or DETA, is an acyclic polyamine used as an epoxy-resin curing agent and a chemical intermediate. It is consumed in the production of reactive polyamide resins, fatty aminoamides, and imidazolines, and serves as a solvent and saponification agent.
Frequently Asked Questions
What is diethylenetriamine used for?
Diethylenetriamine (DETA, CAS 111-40-0) is an acyclic polyamine used as a hardener for two-part epoxy systems and as a chemical intermediate. It is consumed in the production of reactive polyamide resins, fatty aminoamides, and imidazolines, and serves as a solvent and saponification agent. RawSource supplies it in bulk to coatings, adhesive, and surfactant manufacturers.
How is diethylenetriamine made?
DETA is produced industrially as a co-product of the reaction of ethylenediamine routes — typically the amination of ethylene dichloride with ammonia or the reductive amination of monoethanolamine — yielding the linear triamine C4H13N3 alongside related ethyleneamines. It is then distilled to grade.
What is the difference between diethylenetriamine and ethylenediamine?
Ethylenediamine has two amine groups and two carbons, while diethylenetriamine (C4H13N3) has three amine groups across a longer chain, giving it higher functionality. The extra reactive amine makes DETA a more cross-linking epoxy hardener and a richer intermediate for polyamides and imidazolines.
How is diethylenetriamine shipped and packaged?
DETA classifies under UN 2079 for transport and HS 2921.29 (other acyclic polyamines). RawSource supplies it in drums, IBC totes, and bulk, with a current SDS and Certificate of Analysis provided per shipment.
What is the CAS number for diethylenetriamine?
Diethylenetriamine's CAS number is 111-40-0, molecular formula C4H13N3, also referenced as DETA and 2,2'-iminodi(ethylamine). Request a CoA and SDS from RawSource to confirm grade for your application.
