6419-19-8 Usage

Water treatment agent

Amino tris(methylene phosphonic acid), its solid form is crystalline powder, soluble in water, hygroscopic, has excellent chelation, low threshold inhibition and lattice distortion. It has excellent scale inhibition below 200 ℃, low toxicity, good thermal stability, Amino tris(methylene phosphonic acid) can be dissociated into six positive and negative ions in the water, and can form a stable chelate with a variety of metal ions such as iron, copper, aluminum, zinc, calcium, magnesium, etc. It has a more preferable scale inhibition effect on carbonate . And it has good synergy with the polyphosphate, polycarboxylate, nitrite. There are good inhibition when in 40mg/L.

Uses

Different sources of media describe the Uses of 6419-19-8 differently. You can refer to the following data:
1. It is used for power plants, refineries, petrochemicals, fertilizer plant cooling water, oil field injection water system,particularly suitable for hard high-calcium, low concentration multiple systems, such as power plants and high hardness high salinity, bad water quality conditions of the oil pipeline inhibitors,which may decrease the risk of corrosion and scaling of metal equipment and pipeline. In the textile printing and dyeing industry,Amino tris(methylene phosphonic acid) is used as a metal ion chelating agent, metal surface treatment agent. The above information is edited by the lookchem of Tian Ye.
2. A powerful complexing agent. A potent acid sphingomyelinase inhibitor.
3. Nitrilotris(methylene)triphosphonic acid solution was used to study the mechanism of inhibition of cement hydration by phosphonic acid.

Notclassified

Check Digit Verification of cas no

The CAS Registry Mumber 6419-19-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6419-19:
(6*6)+(5*4)+(4*1)+(3*9)+(2*1)+(1*9)=98
98 % 10 = 8
So 6419-19-8 is a valid CAS Registry Number.

, (2021/10/26)

We report here a practical and efficient synthesis of α-aminotrismethylphosphonic acid (ATMP) from (Aminomethyl)phosphonic acid (AMPA) under green conditions using microwave irradiation, via Irani-Moedritzer reaction. The ATMP was characterized by FT-IR, 1H NMR, 13C NMR, 31P-NMR and Elemental Analysis. It was found that the synthesis method gave a higher yield within very short reaction times in comparison with conventional method. In order to know the effect of phosphonomethylation moiety on the structures, electronic, vibrational and thermodynamic and optical properties for AMPA and ATMP molecules were carried out by DFT calculations in gas and water phases. Indeed, stable structures of the two molecules were optimized by using the hybrid B3LYP/6–31 G method and their HOMO-LUMO energy, MESP, global and local reactivity descriptors and NLO properties were calculated. Moreover, antioxidant activity of both investigated compounds was evaluated by DPPH. radical scavenging methods where a strong activity has been found.

Page/Page column 18, (2010/12/26)

A method for the manufacture of aminopolyalkylene phosphonic acid of a specific general formula is described. In particular, a mixture of specifically defined ranges of reactants to wit: phosphorous acid; an amine; formaldehyde and an aminopolyalkylene phosphonic acid, having the same general formula as the compound to be manufactured, are reacted to thus yield a product of outstanding selectivity and purity with substantially reduced levels of non-desirable by-products.
