General Properties

Diethylenetriamine, or DETA, is a colorless liqiud whose temperature is room temperature. It is the simplest cyclic ethylene amin which possesses two secondary amin groups. It dissolves in water and other polar solvents but it does not dissolve in simple hydrocarbons. It is a weak alcali and its aqueous solution is alkaline. It is humectant.

Production

Diethylenetriamine is acquired through catalytic reaction of monoethanolamin and ammonia in high pressure and temperature. It can also be acquired as byproduct from ethylenediamine production.

Applications

Diethylenetriamine is a commonly used curing substance for epoxy glue and other thermoset epoxy resins. It is used for disintegration of hyrogen and sulphur in oil industry. It is used as softener and fixator in textile industry. It is also used in paper, polyamide resin, polyurethane, ion immobilizeri asphalt additive, dye and medicine production. It is also a corrosion blocker.

Safety Measures and Toxic Values

Diethylenetriamine is a toxic chemical for humans. It is irritant for skin and it may cause serious damage to eyes. If it is repeatedly inhaled in high amounts, it may be fatal.
