Diethylenetriamine

Diethylenetriamine (often abbreviated as DETA and also known as 2,2’-Iminodi(ethylamine)) is an organic compound with the formula HN(CH2CH2NH2)2. This colorless liquid is a polyamine, a compound having two or more amino groups. DETA is a structural analogue of diethylene glycol. Its chemical properties resemble those of ethylenediamine, and it has similar uses. It is a weak base and its aqueous solution is alkaline. DETA is a byproduct of the production of ethylenediamine from ethylene dichloride.

Production

DETA is produced industrially from ethylenediamine (EDA) and ethanolamine (EA) via a reaction with ammonia (NH3). The reaction can be described as follows:

EDA + EA + NH3 → DETA

This reaction is catalyzed by a mixture of hydrogen and nitrogen gases.

Applications

DETA is used in a variety of industrial applications. It is used as a solvent for numerous resins and is also used in the production of a variety of chemicals, including textile auxiliaries, paper wet-strength resins, and polyamides. It is also used in the oil industry for the extraction of acid gas.

Safety

DETA is corrosive and can cause burns to the skin and eyes. It is also harmful if swallowed or inhaled. Proper safety precautions should be taken when handling DETA, including the use of personal protective equipment.
