Amino tris(methylene phosphonic acid) Chemical Properties,Usage,Production

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 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 chemicalbook of Tian Ye.
Instructions Amino tris(methylene phosphonic acid) is often used with other organic acid, polylactic acid or salt to form organic water treatment agents for circulating cooling water systems under a variety of different water quality conditions. The amount of 1~20mg/L is preferred; in an amount of 20~60mg/L when used as a corrosion inhibitor .
Amino tris(methylene phosphonic acid)is acidic, pay attention to labor protection, should avoid contact with eye and skin, once contacted, flush with plenty of water.

Chemical Properties colourless liquid
Uses Nitrilotri(methylphosphonic acid) is a common chelating agent used in synthetic chemistry. Some of the other applications include:
- Preparation of hexagonal porous three-dimensional structures encapsulating a template, layered structures with intercalated templates or linear polymers.
- Synthesis of metal-organic frameworks in combination with uranyl nitrate.
- Preparation of ingredient of anticorrosive protective coatings on the steel surface.
- ATMP can also be employed as a scale inhibitor during squeeze treatments in oilfield operations.
Uses Nitrilotris(methylene)triphosphonic acid solution was used to study the mechanism of inhibition of cement hydration by phosphonic acid.
Uses A powerful complexing agent. A potent acid sphingomyelinase inhibitor.
Definition ChEBI: [Nitrilotris(methylene)]trisphosphonic acid is a phosphonoacetic acid.
General Description Nitrilotris(methylene)triphosphonic acid solution is an antiscalant and can be removed form membrane concentrates by iron-coated waste filtration sand. It is a cement retarder. It reacts with the aluminum surface to form a coating which is an effective inhibitor of the reaction of evaporated aluminum thin films on glass or silicon with deionized water.
