DESCRIPTION

Amino Trimethylene Phosphonic Acid, ATMP

CAS No. 6419-19-8

Molecular Formula: N(CH₂PO₃H₂)₃

Molecular weight: 299.05

Structural Formula:

Properties:

ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale formation, calcium carbonate in particular, in water system. ATMP has good chemical stability and is hard to be hydrolyzed in water system. At high concentration, it has good corrosion inhibition.

ATMP is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal power plant and oil refinery plant. ATMP can decrease scale formation and inhibit corrosion of metal equipment and pipeline. ATMP can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent.

The solid state of ATMP is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts. Because of its high purity, it can be used in woven & dyeing industries and as metal surface treatment agent.

Usage and Dosage:

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.

Packing and Storage:

ATMP liquid: Normally 250kgor 550LBS net in drum, 1000kg or 2700LBS net in IBC, or per customers.

ATMP solid:25kginner liner polyethylene (PE) bag, outer plastic woven bag, or confirmed by clients.Storage for ten months in room shady and dry place.

Safety Protection:Acidity, Avoid contact with eye and skin, once contacted, flush with water immediately.

Typical Properties

Amino tris(methylene phosphonic acid) has good chelation, low limit inhibition and lattice distortion, which can prevent the formation of scale salts in water, especially calcium carbonate scale. Amino tris(methylene phosphonic acid) has stable chemical properties in water and is not easy to be hydrolyzed. When the concentration of aminotrimethylene phosphonic acid in water is high, it has good corrosion inhibition effect. This product is mainly used in thermal power plants, refineries of circulating cooling water, oilfield water injection system. It can reduce the corrosion and scaling of metal equipment or pipeline. Amino tris(methylene phosphonic acid) can also be used as chelating agent of metal ions and surface treatment agent of metal ions in textile printing and dyeing industry.
