Disodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid---HEDP•Na2

 

CAS No.: 7414-83-7                                           Molecular Formula: C2H6O7P2Na2     

 

Synonyms: Dequest 2016BD                             Molecular Weight: 250

 Etidronate Disodium, CubleK2012

 

Properties:

HEDP•Na2 chelates with Fe, Cu, and Zn ions and can dissolve the oxidized materials. It shows good scale and corrosion inhibition effects and obvious dissolution threshold effects. Even under 250℃, under high pH value, it is quite stable and not easy to be hydrolyzed, not easy to be decomposed under normal light and heat condition.

HEDP•Na2 shows better acid/alkaline and chloride oxidation tolerance than other phosphonates. It can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. It has better synergistic effects.
