Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium Salt is an organophosphonate water treatment chemical with CAS No. 22036-77-7. It is the sodium salt product formed by neutralizing Ethylene Diamine Tetra (Methylene Phosphonic Acid) with sodium hydroxide or other alkaline agents. Its molecular structure contains multiple phosphonic acid groups and nitrogen-containing coordination sites, giving it strong complexing and chelating ability toward metal ions such as calcium, magnesium, iron, and copper. Therefore, it mainly functions as a corrosion inhibitor, scale inhibitor, dispersant, and stabilizer in water treatment systems. Compared with conventional inorganic phosphates, Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium Salt offers better hydrolysis resistance, thermal stability, and complexing performance, and can be classified into pentasodium salt, heptasodium salt, and octasodium salt according to the degree of neutralization.

The upstream raw materials of Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium Salt mainly include ethylenediamine, formaldehyde, phosphorous acid or phosphorus trichloride, and sodium hydroxide. Ethylenediamine provides the nitrogen-containing backbone, while formaldehyde and the phosphorus source participate in the phosphonomethylation reaction, followed by neutralization to produce different sodium salt products. Its downstream applications mainly cover water treatment, metal surface treatment, textile dyeing and printing, and industrial cleaning. It is widely used in circulating cooling water, boiler water, oilfield injection water, cyanide-free electroplating, peroxide bleaching stabilization, and cleaning formulations. The product is usually used as a supplementary organophosphonate alongside HEDP, ATMP, DTPMP, and related systems, especially in formulations requiring strong chelation, scale inhibition, dispersion performance, and adaptability to high-hardness water.

Global key Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium Salt players cover Italmatch Chemicals, Zschimmer & Schwarz, Shandong Taihe Technologies, Shandong Kairui Chemistry, Shandong ThFine Chemical, etc.
