Diethylene Triamine Penta (Methylene Phosphonic Acid)
(DTPMPA, ZF114)
CAS No 15827-60-8 Dequest 2060
Molecular Formula: C9H28O15N3P5 Molecular weight: 573.2
Structural Formula:
Properties:
This product is innocuous, easy to be dissolved in acid solution, it has excellent antiscale corrosion inhibition and good thermal resistance effects. DTPMPA can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature ( above 210¡æ) this product has better antiscale corrosion inhibition effect than other organophosphines.
