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. In the alkali environment and high temperature (above 210℃), DTPMPA has a better scale and corrosion inhibition effect than other organophosphines.

Usage:
DTPMPA can be used as a scale and corrosion inhibitor in circulating cool water systems and boiler water, especially in alkali circulating cool water systems without additional pH regulation. It can also be used in oilfield refill water, cool water, and boiler water with a high barium carbonate concentration. When used alone, little scale sediment is found even none of dispersant is used.
DTPMPA can also be used as peroxide stabilizer, a chelating agent in the woven & dyeing industry, pigment dispersant, microelement’s carrying agent in fertilizer, and concrete modifier. Besides, DTPMPA is used in papermaking, electroplating, acid cleaning, and cosmetics.
