ATMP amino trimethylene phosphonic acid

[CAS]6419-19-8
Synonym: Amino trimethylene phosphonic acid Dequest: 2000
Formula N (CH3PO3H3) 3C molecular weight: 299.05
1, Properties and Uses:
ATMP has excellent chelation, low threshold inhibition and lattice distortion. Can prevent the formation of scale salt water into the dirt, especially calcium carbonate scale formation.
ATMP
in water and chemically stable, hard to be hydrolyzed. High concentration in the water, good inhibition effect.
ATMP
for the power plant, refinery cooling water, oil field injection water system. Could serve to reduce corrosion of metal equipment and pipeline and the role of scaling.
ATMP
in the textile and dyeing industry as a metal chelator, can also be used for metal surface treatment agent. solid as crystalline powder, soluble in water, easy to absorb moisture, easy to transport and use, especially for cold areas in winter. Because of high purity can be used as textile printing and dyeing industry, metal chelating agents and metal surface treatment agent.

3, Application Usage
ATMP
often associated with other organic phosphoric acid, polycarboxylic acid or salt compound dubbed organic alkaline water treatment agent, for a variety of different water quality conditions in the circulating cooling water system. The dosage of 1 ~ 20mg / L is preferred; as corrosion inhibitor used, the dosage of 20 ~ 60mg / L.
