ATMP (Nitrilotrimethylphosphonic Acid (Solution of Amino tri (methylene phosphonic acid)

Chemical Formula: С3Н12NO9P3

CAS № 6419-19-8

Manufacturer: China

Appearance: Clear, colorless or pale yellow aqueous solution

Chemical name (synonyms):

  • Amino trimethylene phosphonic acid;
  • Amino tri (methylene phosphonic acid);
  • Tri (methylene phosphonic acid) amine;
  • Nitrilotrimethylphosphonic Acid (NTP);
  • Nitrilotrimethylenetris (phosphonic acid).

Description and application:

Nitrilotrimethylphosphonic acid has excellent chelation, low threshold inhibition, and the ability to distort the lattice. This can prevent the formation of scale, in particular calcium carbonate, in the water system. The product has good chemical stability and is difficult to hydrolyze in the water system. At high concentrations, it has good corrosion inhibition.Used in industrial circulating cool water and oilfield water pipelines in the fields of thermal power plant and oil refinery. It can reduce scale formation and prevent corrosion of metal equipment and pipeline. Nitrilotrimethylphosphonic acid can be used as a chelating agent in the textile and dyeing industries, as well as as an agent for metal surface treatment.
