CAS No. 15827-60-8
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.
Specification of DTPMPA
Items | Index |
Appearance | Brown transparent liquid |
Active acid % | 50.0 min |
Chloride (as Cl-)% | 12.0-17.0 |
Density (20℃) g/cm3 | 1.35-1.45 |

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.
