Tetraethylene pentamine is a chemical compound from the group of polyamines , more precisely the polyethyleneamines .

Extraction and presentation

Tetraethylene pentamine can be obtained by heating diethylenetriamine with 1,2-dichloroethane and aqueous ammonia . It is also a by-product of making ethylenediamine from 1,2-dichloroethane and ammonia.

use

Tetraethylene pentamine is used as a peroxide activator in 1,3-butadiene polymerisation, for the production of aminoplasts and ion exchange resins . It is a hardener for epoxy resins and is used in flame retardants . The compound is used for the synthesis of textile auxiliaries and detergents . Tetraethylene pentamine is a solvent for sulfur, acid gases, resins, dyes and a dispersing agent in motor oils. It is used in galvanic baths and as a ceramic, cement and concrete additive. Tetraethylene pentamine is also used as a ligand in metal complexes.

Polyaminoboronates, which are used as crosslinkers for guar gum, can be obtained from boric acid , ethylene glycol and tetraethylene pentamine.
