Soild HEDP 1-Hydroxyethylidene-1,1-diphosphonic acid C2H8O7P2
CAS NO.:2809-21-4
SYNONYMS: Dequest 2010, Etidronic Acid
HEDP is an organophophoric acid inhibitor. It can chelate with Fe, Cu, and Zn ions to form scale chelating compounds. It can dissolve the oxidized materials on these metal¡¯s surfaces. It 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, it has good antiscale and visible threshold effects.
Solid HEDP is crystal powder, suitable for usage in winter and freezing district. Due to its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals.

Usage:
HEDP is used as scale and corrosion inhibition, often built with polycarboxylic acid, in circulating cool water system, oil field and low pressure boilers in fields such as electric power, hcemical industry, metallurgy, fertilizer, etc.
In light woven industry, HEDP is used as ***ergent for metal and nonmetal. In dyeing industry, it i s used as peroxide stabilizer and dye-fixing agent; in non-cyanide electronplating, is is used as chelating agent.
