Aminotris (methylene phosphonic acid) (ATMP)
CAS NO.:6419-19-8
Molecular Formula: N(CH2PO3H2)3
Synonyms: Nitrilotrimethanephosphonic acid, Dequest 2000.
Structural Formula
ATMP is an effective scale inhibitor used in various industrial applications such as industrial water treatment and detergents. It further shows good corrosion inhibition properties in presence of zinc and other phosphates. ATMP can be also used as chelating agent in the textile industry.
Applications:
Cooling water systems / industrial water treatment
Industrial detergents
Metal surface treatment as corrosion inhibitor for steel
Stabilizer in H2O2 solutions
Sequestering agent in textile auxiliaries
Usage:
ATMP is usually used together with organophosphoric acid, polycarboxylic acid and salt to built all organic alkaline water treatment agent. ATMP can be used in many different circulating cool water system. The dosage of 1-20mg/L is recommended. As corrosion inhibitor, the dosage of 20-60mg/L is preferred.
