Detailed Product Description

Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA)

CAS No 15827-60-8 Dequest: 2060

Molecular Formula: C9H28O15N3P5 Molecular weight: 573.2

Properties:
DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability. DTPMPA can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature (above 210?) DTPMPA has better scale and corrosion inhibition effect than other organophosphines.
