Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA)
CAS No 15827-60-8 Dequest 2060
Molecular Formula: C9H28O15N3P5 Molecular weight: 573.2
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.

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
carbonate. 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.
