The formula



Diethylenetriamine (abbreviated DETA and also known as 2,2’-Iminodi(ethylamine) is an organic compound with the formula HN(CH2CH2NH2)2. This colourless hygroscopic liquid is soluble in water and polar organic solvents, but not simple hydrocarbons. Diethylenetriamine is structural analogue of diethylene glycol.

1. It is used as an intermediate for organic synthesis (modified polyamides, corrosion inhibitors, fuel additives, epoxy curing agents, fabric softeners and adhesion promoters) and saponification agent for acidic materials. It is used as a solvent for sulfur, acidic gas, resin and as a fuel and oil field component

2. Chelating agents to form complexes with certain metal ions to prevent the ions from interfering with processing or to promote buffering, concentration, separation, or transport

3. Corrosion inhibitors to slow corrosion in petroleum production operations
