Thermodynamic Parameters for the Formation of Pyrophosphate-protonated Polyamine Complexes

Abstract

This work reports thermodynamic parameters for the complex formation of pyrophosphate-protonated amines (ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine and pentaethylenehexamine): as already found for log K, the TΔS° parameter also shows a linear dependence on the charges involved in the formation reaction.
