Abstract

Complexation reactions of the Fe (III) cation by seven oxaalkyl phosphate esters and ethyl phosphate in ethanol were studied by kinetic methods, as well as 31P NMR and semi- empirical methods. The ΔG≠ values for almost all phosphates were in the range of 53– 56kJmol− 1. The greatest differences were observed for the ΔS≠ values of the systems studied, whereas the enthalpies of activation ΔH≠ were compensated by the entropy of ...
