Phosphonates

We offer an excellent quality range of Phosphonates. DTPMP or diethylenetriamine penta(methylene phosphonic acid) is a phosphonic acid. It has chelating and anti corrosion properties.
DTPMP is normally delivered as salts, because the acid form has very limited solubility in water and tends to crystallize in concentrated aqueous solutions. It is a nitrogenous organic polyphosphonic acid. It shows very good inhibition of the precipitation of barium sulfate (BaSO4). At high alkali and high temperature (above 210 A C) environments DTPMPA has better scale and corrosion inhibition effect than other phosphonates.
1-hydroxyethane 1,1-diphosphonic acid (HEDP) is a bisphosphonate used in detergents, water treatment, cosmetics and pharmaceutical treatment.
An etidronate is a salt of etidronic acid, abbeviated MnHEDP (M: is a cation, n: number of M maximum 4).
Etidronic acid is a chelating agent and may be added to bind or, to some extent, counter the effects of substances, such as calcium, iron or other metal ions, which may be discharged as a component of grey wastewater and could conceivably contaminate groundwater supplies. As a phosphonate it has corrosion inhibiting properties on unalloyed steel. Etidronic acid also acts to retard rancidification and oxidation of fatty acids.
