DTPMP

Product Details

Diethylene Triamine Penta (Methylene Phosphonic Acid)

DTPMP

(Certified by NSF STANDARD 60 and Passed REACH Pre-registration)

CAS Number: 15827-60-8

Molecular Formula: C9H28N3O15P5

Molecular Weight: 573

Application Notes:

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

Recommended Uses:

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

DTPMP 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, DTPMP is used in papermaking, electroplating, acid cleaning and cosmetics.
