DTPMPA DIETHYLENE TRIAMINE PENTA (METHYLENE PHOSPHONIC ACID)

Product Description

DTPMPA is an organo phosphonic acid compound exhibiting excellent sequestration of metal ions at stoichiometric concentration and threshold inhibition of metal salt precipitation at sub-stoichiometric concentrations. The ability of DTPMPA to deflocculate or disperse solid particles combined with its temperature and hydrolytic stability makes it a versatile ingredient for applications requiring efficient metal ion (like Fe/Fe) control.

DTPMPA (Diethylenetriamine Penta Methylene Phosphonic Acid) is a highly effective organophosphonic acid used globally as a scale and corrosion inhibitor. Its strong chelating properties make it invaluable for treating water systems in power plants, oilfields, and textile processing.

Core Properties

• Formula: C9 H28 N3 O15 P5
• Molecular Weight: 573.198 g/mol
• CAS Number: 15827-60-8
• Appearance: Usually supplied as a brown or amber transparent liquid (typically ~50% active acid)

Key Advantages

• High-Temperature Stability: Excels in harsh, high-alkaline environments and temperatures above 210 C.
• Scale Inhibition: Highly effective at preventing carbonate, sulfate, and phosphate scaling.
• Metal Sequestration: Binds strongly with metal ions (like calcium and iron) to prevent pipeline and equipment degradation.

Primary Applications

• Industrial Water Treatment: Used in cooling water and boiler systems to prevent scale formation without needing pH adjustments.
• Oil & Gas Extraction: Helps with flow assurance and water refilling processes in oilfields, even with high mineral and barium concentrations.
• Peroxide Bleaching: Acts as a stabilizer for hydrogen peroxide in textile and pulp industries.
• Metal Cleaning: Prevents corrosion on metal surfaces during various industrial manufacturing processes.
