Dtpmpa High Temperature Resistant Scale And Corrosion Inhibitor For Multi Industry Applications - China

DTPMPA (Diethylene Triamine Penta (Methylene Phosphonic Acid)) – High-Temperature Resistant Scale & Corrosion Inhibitor for Multi-Industry Applications

DTPMPA is a high-performance organophosphonic agent renowned for its excellent temperature resistance, scale/corrosion inhibition, and multi-scenario adaptability.

It is a trusted solution for global B2B partners (including water treatment, oilfield, textile, and chemical enterprises) across diverse industrial workflows.

Basic Product Information

• Chemical Name: Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA)

• CAS No: 15827-60-8

• Molecular Formula: C₉H₂₈O₁₅N₃P� �

• Relative Molecular Mass: 573.2

Performance & Applications

Core Performance

DTPMPA is non-toxic and readily soluble in acidic solutions, with standout advantages:

• Excellent scale & corrosion inhibition; effectively suppresses carbonate and sulfate scale formation.

• Superior temperature resistance: Maintains stable performance above 210℃, outperforming other organophosphates in alkaline environments and high-temperature conditions.

Key Application Scenarios

1 - Water Treatment Sector: ◦ Used as a scale & corrosion inhibitor for circulating cooling water and boiler water systems.

Especially suitable as a pH-unadjusted agent for alkaline circulating cooling water; ideal for oilfield water injection (high barium carbonate content) and boiler/cooling water scale/corrosion control.

◦ When used alone in compound formulations, no additional dispersants are needed – scale deposition remains minimal.

2 - Cross-Industry Uses: ◦ Peroxide stabilizer (excellent stability for hydrogen peroxide under high temperatures).

◦ Textile dyeing chelating agent, pigment dispersant, oxygen delignification stabilizer, fertilizer trace element carrier, and concrete additive.

◦ Widely applied in papermaking, electroplating, metal pickling, cosmetics; also serves as a stabilizer for oxidative bactericides.
