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.
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.
Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2.The pure free base is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air oxidation.
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]
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).
Ethylene dichloride is reacted with ammonia as a main method of production. This process produces various ethylene amines which can then be purified by distillation. These include ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, other higher homologues and aminoethyl piperazine.
