Uses

Used in Water Treatment:
[Nitrilotris(methylene)]trisphosphonic acid N-oxide is used as a chelating agent for [enhancing the removal of metal ions from water systems]. Its phosphonic acid group allows it to bind effectively with metal ions, facilitating their removal and preventing the formation of scale and deposits in water treatment processes.
Used in Scale and Corrosion Inhibitors:
In the industry of scale and corrosion inhibitors, [nitrilotris(methylene)]trisphosphonic acid N-oxide is used as a preventative agent for [protecting surfaces from scale buildup and corrosion]. Its ability to chelate metal ions helps in reducing the formation of scale, while its reactivity with other atoms contributes to the formation of protective layers that inhibit corrosion.
Used in Detergent Formulations:
[Nitrilotris(methylene)]trisphosphonic acid N-oxide is used as a cleaning agent in detergent formulations for [enhancing the cleaning power and preventing metal ion-induced stains]. Its chelating properties help in removing metal ions that can cause stains, while its reactivity ensures effective cleaning of various surfaces.

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.

METHOD FOR THE SYNTHESIS OF ALPHA-AMINOALKYLENEPHOSPHONIC ACID

The present invention is related to a new method for the synthesis of alpha-aminoalkylenephosphonic acid or its phosphonate esters comprising the steps of forming a reaction mixture by mixing a P-O-P anhydride moiety comprising compound, having one P-atom at the oxidation state (+111) and the other P-atom at the oxidation state (+111) or (+V), an aminoalkanecarboxylic acid and an acid catalyst, wherein said reaction mixture comprises an equivalent ratio of alpha-aminoalkylene carboxylic acid to P-O-P anhydride moieties of at least 0.2, and recovering the resulting alpha-aminoalkylene phosphonic acid compound or an ester thereof from the reaction mixture.

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.
