Tetraethylenepentamine (TEPA) is an organic compound and is in the class of chemicals known as ethyleneamines. It is a slightly viscous liquid and is not colorless but, like many amines , has a yellow color.
Polyethylenimine (PEI) or polyaziridine is a polymer with repeating units composed of the amine group and two carbon aliphatic CH 2 CH 2 spacers. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups.
Pentaethylenehexamine (abbreviated PEHA) is an organic amine.It is composed of five ethylene groups-CH 2 CH 2 - joined together in a chain by four secondary amine groups (-NH-) and terminated on each end by primary amine groups (-NH 2).
Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C 2 H 4 (NH 2) 2.This colorless liquid with an ammonia-like odor is a basic amine.It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. [6]
Colestipol is a copolymer of diethylenetriamine (DETA) —or tetraethylenepentamine according to some sources [5] [6] — and epichlorohydrin. [ 7 ] [ 8 ] The structure drawing (top right) shows the DETA moieties in blue and the epichlorohydrin moieties in red.
The amine value is useful in helping determine the correct stoichiometry of a two component amine cure epoxy resin system. [6] [7] [8]It is the number of Nitrogens x 56.1 (Mwt of KOH) x 1000 (convert to milligrams) divided by molecular mass of the amine functional compound.
