Pentaethylenehexamine (abbreviated PEHA) is a organic amine. It is composed of five ethylene groups -CH2CH2- joined together in a chain by four secondary amine groups (-NH-) and terminated on each end by primary amine groups (-NH2). Pentaethylenehexamine is a hexadentate ligand, owing to the Lewis basicity of the six amine groups.[3] Pentaethylenehexamine is in the category of polyethyleneamines and is part of mixtures of these sold commercially.[2]
Commercial supplies of pentaethylenehexamine contain, in addition to the linear form, branched and cyclic polyamines.[2] As an amine, it is an organic base and can form ammonium salts by reaction with various acids. Salts with counter-anions such as chloride, sulfate, nitrate, naphthalene-2-sulfonate, and tosylate. Tosylate salts can be used to separate the linear molecule from the other forms, as it is less soluble.[2]
