Aminotrimethylene phosphonic acid (ATMP)
CAS No. 6419-19-8
Alias: aminotrimethylenephosphonic acid, ATMPA, nitrilotrimethylenetriphosphonic acid, nitrilotrimethylenephosphonic acid
Molecular formula N(CH2PO3H2)3 Relative molecular mass: 299.05
1. performance and use:
ATMP has good chelation, low-limit inhibition and lattice distortion. It can prevent the formation of scale, especially calcium carbonate scale, from scale-forming salts in water. ATMP is chemically stable in water and is not easily hydrolyzed. When the concentration in water is high, it has a good corrosion inhibition effect.
ATMP is used in thermal power plants, refinery circulating cooling water, and oilfield refilling systems. It can reduce the corrosion and scaling of metal equipment or pipelines. ATMP is used as a metal ion chelating agent in textile printing and dyeing industries, and can also be used as a metal surface treatment agent.
ATMP solid is white granular, soluble in water, easy to absorb moisture, easy to transport and use, especially suitable for cold winter areas.
2. technical indicators
3. the method of use
ATMP is often combined with other organic phosphonic acids, polycarboxylic acids or salts to form an organic water treatment agent for circulating cooling water systems under various water quality conditions. The dosage is preferably from 1 to 20 mg/L; when used as a corrosion inhibitor, the amount is from 20 to 60 mg/L.
4. packaging and storage
ATMP liquid is packed in plastic drums, 30kg or 250kg per barrel; ATMP solids are packed in plastic woven bags lined with polyethylene bags, each bag has a net weight of 25kg, which can also be determined according to user needs. Store in a cool and ventilated place indoors, prevent moisture and prevent exposure, and store for 12 months.
5. security protection
ATMP is acidic. Pay attention to labor protection during operation. Avoid contact with skin and eyes. Rinse with plenty of water immediately after contact.
