CAS No.: 15827-60-8
Other Name: DETPMP
Molecular Formula: C9H28O15N3P5
Molecular Weight: 573.2
DTPMPA is non-toxic, easy to dissolve in acid solution. It can chelate with Ca, Mg and Cu to form stable chelating complex. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance. 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 organic phosphorus .

DTPMPA can be used as scale and corrosion inhibitor in circulating cooling water and boiler water, and especially in alkali circulating cooling water system without additional pH regulation. It can also be used in oilfield injection water, cooling water and boiler water with high concentration of barium carbonate. When used alone, little sediment is found, even none of dispersant is used.
DTPMPA can also be used as peroxide stabilizer, chelating agent in textile & dyeing industry, pigment dispersant, microelement carrying agent in fertilizer and concrete modifier. In addition, DTPMPA is used in papermaking, electroplating, acid cleaning and cosmetics.
Package and Storage:
200L plastic drum, IBC (1000L), or as customers’ requirements. Storage for ten months in shady room in dry places.
DTPMPA is acidic. Avoid contact with eye and skin. In case of contact with eyes or skin, rinse immediately with plenty of clean water.
