General Description

"[Nitrilotris(methylene)]trisphosphonic acid N-oxide" is a chemical compound with phosphonic acid and nitrile groups, along with an oxide functional group. The molecule has a high potential for complexing with a variety of metal ions, which makes it applicable in areas like water treatment, scale and corrosion inhibitors, and detergent formulations. Its phosphonic acid group contributes to its excellent chelating properties, enabling it to bind tightly to metal ions. Meanwhile, the nitrile group makes it capable of forming multiple bonds with other atoms, increasing its reactivity. Its oxide group allows it to act as a base and to form salts, further expanding its versatility.

Nitrilotri(methylenephosphonic acid) N-oxide and nitrilotriacetic acid N-oxide: Acidity and complexing of calcium and magnesium ions

The synthesis and aqueous stability of nitrilotri(methylenephosphonic acid) N-oxide are reported. Its acidity constants and calcium and magnesium stability constants are reported in addition to those for nitrilotriacetic acid N-oxide. Available information, including 1H and 31P nmr measurements as a function of the number of bound protons, indicates these ligands exist as dipolar ions in solution.

Mechanisms of Peroxide Stabilization. An Investigation of some Reactions of Hydrogen Peroxide in the Presence of Aminophosphonic Acids

It has been established by continuous-flow studies in conjunction with EPR spectroscopy that the aminophosphonic acids 1-4 accelerate significantly the Fenton reaction between Fe(II) and H2O2 in aqueous solution via complexation of the metal ion (with values of the rate constant k for the generation of the hydroxyl radical up to 2 * 105 dm3 mol-1 s-1 at room temperature).To a certain extent this behaviour parallels that of EDTA and some structurally-related aminocarboxylic acids.It is also shown that the N-oxides of the aminophosphonic acids 1-3 react readily with the hydroxyl radical to give long-lived nitroxides via β-scission of first-formed carbon-centred radicals.Neither of these findings is believed to correspond to the major chemistry which underlies the efficacy of these ligands as peroxide stabilizers.It is suggested instead that the crucial role of these compounds depends upon their ability to stabilize the higher valence state of iron, and hence not only to encourage oxidation of Fe(II) by O2.- and H2O2 but also to prevent effective reduction of Fe(III) by O2.-, HO2. and H2O2.However, radical scavenging by N-oxides may be a secondary, contributory factor in this stabilizing function, especially in peroxide systems when the sequestrant is added before storage, when slow N-oxidation is to be expected.
