CAS No. 20592-85-2
Molecular formula C3H8NO9P3Na4
Relative molecular mass: 387
Structural formula
Ⅰ. Performance and use:
ATMP·Na4 is the neutral sodium salt of ATMP, which can prevent scaling salts from forming scale in water, especially the formation of calcium carbonate scale. ATMP·Na4 is suitable for circulating cooling water of thermal power plant, oil refinery, oil field water injection system and scale inhibitor of reverse osmosis membrane. ATMP·Na4 also has good compatibility with some other additives. ATMP·Na4 is especially suitable for neutral to acidic formulations without ammonia flavor.
