Disodium Salt of 1-Hydroxy Ethylidene-1, 1-Diphosphonic Acid Product Description

CAS No.  7414-83-7                                  
Molecular Formula: C2H6O7P2Na2            Molecular weight: 250 
Synonyms: Dequest 2016BD, Etidronate Disodium, CubleK2012
 Structural Formula: 

Properties:
HEDP?Na2 is an organophosphonic acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions, and dissolve the oxidized materials. This salt has good scale and corrosion inhibition effects even under 250oC.
HEDP?Na2 is stable under high pH value, not easy to be hydrolyzed, not easy to be decomposed under normal light and heat condition. Its acid/alkaline and chloride oxidation tolerance are better than that of other organophosph-onic acids. 
HEDP?Na2 can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. It has good scale inhibition effects and obvious dissolution threshold effects. When used with other Water Treatment Chemicals, the synergistic effect is better. 
Disodium Salt of 1-Hydroxy Ethylidene-1, 1-Diphosphonic Acid Specification:

Usage:
HEDP?Na2 is widely used in circulating cool water system, medium and low pressure boiler, oil field water pipelines as scale and corrosion inhibitor in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.
HEDP?Na2 is used as detergent for metal and nonmetal in light woven industry while in dyeing industry, it is used as peroxide stabilizer and dye-fixing agent. In non-cyanide electroplating, HEDP?Na2 is used as chelating agent.
