1-Hydroxy Ethylidene-1,1-Diphosphonic Acid
HEDP
CAS No. 2809-21-4 Dequest:2010
Molecular Formula: C2H8O7P2 Molecular weight: 206.02
Structural Formula:
Properties:
HEDP is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds.It can dissolve the oxidized materials on these metals�surfaces. HEDP shows excellent scale and corrosion inhibition effects under temperature 250� HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.
