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

Uses:
DTPMPA can be used as a scale and corrosion inhibitor in circulating cool water systems and boiler water. And especially in alkali circulating cool water system, DTPMP acid can be used without additional pH regulation. It can also be used in oilfield refill water, cool water, and boiler water with a 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 a peroxide stabilizer, a chelating agent in the 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.
