Synonym: Tetra sodium salt of amino trimethlene phosphonic acid
Molecular Formula: C3H13NNaO9P3
Structural formula:

1.Performance and usage
ATMP·Na4 is the neutral sodium salt of ATMP, which can prevent scale-forming salts in the water from forming scale, especially the formation of calcium carbonate scale. ATMP·Na4 is suitable for circulating cooling water in thermal power plants and refineries, oil field reinjection water systems, and as a scale inhibitor for reverse osmosis membranes. ATMP·Na4 also has good compatibility with other additives. ATMP·Na4 is especially suitable for neutral to acidic formulas without producing ammonia smell.
