Phosphoman 235 DTPMPA - 50%, CAS No. : 15827-60-8

PHOSPHOMAN-235 is an organo-phosphonic acid compound exhibiting excellent sequestration of metal ions at stoichiometric concentration and threshold inhibition of metal salt precipitation at sub-stoichiometric concentrations. The ability of PHOSPHOMAN-235 to de-flocculate or disperse solid particles combined with its temperature and hydrolytic stability makes it a versatile ingredient for applications requiring efficient metal ion (like Fe²/Fe³) control.

It is a nitrogenous organic polyphosphonic acid. It shows very good inhibition of the precipitation of barium sulfate (BaSO4) as well as Strontium Sulfate (SrSO4). At high alkali and high temperature (above 210 °C) environments DIETHYLENE TRIAMINE PENTA(METHYLENEPHOSPHONIC) ACID has better carbonate, sulfate, and phosphate scale and corrosion inhibition effect than other phosphonates.
