HEDP (1-Hydroxy Ethylidene-1,1-Diphosphonic Acid)

CAS No. 2809-21-4

HEDP is an organophosphoric acid corrosion inhibitor. HEDP can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. HEDP can dissolve the oxidized materials on these metals surfaces. HEDP shows excellent scale and corrosion inhibition effects under temperature 250centigrade. 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.
The solid state of HEDP is crystal powder, suitable for usage in winter and freezing districts. Because of its high purity, HEDP can be used as cleaning agent in electronic fields and as additives in daily chemicals.
