EDTMPS is nitrogen‑containing organic polyphosphonate, belonging to cathodic corrosion inhibitor. Its corrosion‑inhibition efficiency is 3‑5 times higher than inorganic polyphosphates. It is miscible with water, non‑toxic and pollution‑free. It features good chemical stability and thermal resistance, and maintains excellent scale‑inhibiting performance at 200 ℃. It dissociates into 8 positive and negative ions in aqueous solution, so it can chelate with multiple metal ions to form macromolecular network complexes, which disperse loosely in water and disrupt normal crystal growth of calcium scale. It delivers favorable scale‑inhibiting effect against calcium sulfate and barium sulfate scale.
Alias: Sodium Ethylene Diamine Tetramethylene Phosphonate
Molecular Formula: C₉H₂₈O₁₅N₃P₅
Relative Molecular Mass: 612.13

EDTMPS is used as corrosion and scale inhibitor for circulating water and boiler water, chelating agent for non‑cyanide electroplating, chelator and oxygen‑bleaching stabilizer in textile printing & dyeing industry.
| Item | HG/T3538‑2011 |
|---|---|
| Appearance | Light‑yellow to yellow transparent liquid |
| Active Component (as EDTMPS) % | ≥30.0 |
| Organic Phosphorus (as PO₄³⁻) % | ≥10.0 |
| Phosphorous Acid (as PO₃³⁻) % | ≤3.0 |
| Phosphoric Acid (as PO₄³⁻) % | ≤1.0 |
| Density (20℃) g/cm³ | ≥1.25 |
| Chloride (as Cl⁻) % | ≤2.0 |
| pH (1% aqueous solution) | 9.5‑10.5 |
When dosed alone in circulating cooling water, the typical dosage is 2‑10 mg/L. EDTMPS compounded with HPMA at 1:3 ratio can be applied for low‑pressure boiler water treatment. It can also be compounded with BTA, PAAS, zinc salts, etc.
Packed in plastic drums, 25 kg per drum; customized packages are available upon customer requirements. Store indoors in cool place. Shelf life: 6 months.
EDTMPS is weakly alkaline. Take labor‑protection measures during operation. Avoid contact with skin and eyes. Rinse immediately with plenty of clean water in case of contact.
