Diethylene Triamine Penta (Methylene Phosphonic Acid)

(DTPMPA)

CAS No.  15827-60-8

Molecular Formula: C9H28O15N3P5             Molecular weight: 573.2

Structural Formula:

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.CDTPMPA 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, It can 

also be used in oilfield refill water, cool water and boiler water with high concentration of barium c

arbonate. When used alone, little scale sediment is found even none of dispersant is used.

DTPMPA 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.
