ATMP/ATMPA (CAS 6419-19-8)
ATMP/ATMPA (CAS6419-19-8)
Full Name:Amino Trimethylene PhosphonicAcid
Molecular Formula: N(CH2PO3H2)3
Molecular Weight: 299.05
Structural Formula:
Properties
ATMP has great chelation, low threshold inhibitionand lattice distortion functions. It can effectivelyprevent scale formation in water, especially calcium carbonate scale. ATMPA offers superior chemical stability and is difficult tobe hydrolyzed. Higher concentration of ATMPA (inwater) can result in better corrosion inhibition.
Applications
As Amino Trimethylene Phosphonic Acid is ideal for scale formation reduction and corrosioninhibition of metal equipment and pipelines, it is widely used in oilfield re-injection water systems and circulating cooling water systems in thermal power plants, oil refineries, etc. Inaddition, ATMP can also be used as metal surface treatmentagent as well as metal ion chelating agent in the textile, printing anddyeing industries.

User Guide
1. When ATMP iscompounded with other organic phosphonic acid, poly carboxylic acid or salt to form an organic water treatment chemical foruse in cooling water systems, the recommended dosage is 1-20mg/L.
2. When ATMPA is used as a corrosion inhibitor,the dosage of 20-60mg/L is preferred.
Packing
