Organophosphoric Antiscale and Corrosion Inhibitors, Chelant

Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA)

CAS No.  15827-60-8

Molecular Formula: C9H28O15N3P5

Molecular weight: 573.2

Structural Formula:

Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA) Structural Formula

Properties:

DTPMPA is innocuous, easy to be dissolved in acid solution. it 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℃) Diethylene Triamine Penta (Methylene Phosphonic Acid) has better scale and corrosion inhibition effect than other organophosphines.

Usage:

DTPMPA can be used as scale and corrosion inhibitor in circulating cool water system and boiler water, and especially in alkali circulating cool water system without additional pH regulation, Diethylene Triamine Penta (Methylene Phosphonic Acid) can also be used in oilfield refill water, cool water and boiler water with high concentration of barium carbonate. When used alone, little scale sediment is found even none of dispersant is used.

Diethylene Triamine Penta (Methylene Phosphonic Acid) can also be used as peroxide stabilizer, chelating agent in woven & dyeing industry, pigment dispersant, microelement’s carrying agent in fertilizer and concrete modifier. In addition, DTPMPA is used in papermaking, electroplating, acid cleaning and cosmetics.
