DTPMPA is non‑toxic and soluble in acidic solutions. It delivers excellent scale‑inhibiting and corrosion‑inhibiting performance with good thermal stability, and can suppress the formation of carbonate and sulfate scales. Under alkaline conditions and high temperature (above 210 ℃), its scale and corrosion inhibition outperforms other organophosphonic acids. In water treatment, it serves as scale and corrosion inhibitor for circulating cooling water and boiler water. DTPMPA is especially suitable for alkaline circulating cooling water as scale‑corrosion inhibitor without pH adjustment. It is also applicable for oilfield injection water, cooling water and boiler water with high barium carbonate content. When used alone in compound formulations, little dirt deposition occurs without additional dispersant.
Alias: Diethylenetriamine Pentamethylenephosphonic Acid
Molecular Formula: C₉H₂₈O₁₅N₃P₅
Relative Molecular Mass: 573.2

DTPMPA can also act as peroxide stabilizer (excellent stabilizing effect for hydrogen peroxide under high‑temperature conditions), chelating agent for textile printing & dyeing, pigment dispersant, oxygen‑delignification stabilizer, trace‑element carrier for fertilizer, and concrete additive. Furthermore, it is widely applied in papermaking, electroplating, metal pickling, cosmetics, and can be used as stabilizer for oxidative biocides.
| Item | HG/T 3777‑2005 |
|---|---|
| Appearance | Brown‑yellow to reddish‑brown viscous liquid |
| Active Component (as DTPMPA) % | ≥50.0 |
| Phosphorous Acid (as PO₃³⁻) % | ≤3.0 |
| Density (20℃) g/cm³ | 1.35‑1.45 |
| Chloride (as Cl⁻) % | 12‑17 |
| pH (1% aqueous solution) | ≤2.0 |
| Iron (as Fe²⁺) content, mg/L | ≤35.0 |
For scale inhibition, normal dosage ranges from 1‑30 mg/L; for cleaning agent, typical dosage is 1000‑2000 mg/L. It is usually compounded with polycarboxylic scale dispersants. Dosage shall be determined by tests for applications in other industries.
Normally packed in plastic drums of 25 kg or 30 kg; customized packages available upon request. Store indoors in cool place. Shelf life: 12 months.
DTPMPA is acidic. Take labor‑protection measures during operation. Avoid contact with skin and eyes. Rinse immediately with plenty of clean water upon contact.
