PEHA meaning in Chemistry ?

Answer:

What is Pentaethylenehexamine mean?

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. Pentaethylenehexamine is in the category of polyethyleneamines and is part of mixtures of these sold commercially.

Commercial supplies of pentaethylenehexamine contain, in addition to the linear form, branched and cyclic polyamines. 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.
