Product Description
CAS NO. 7414-83-7
Dequest 2016BD
Molecular Formula: C2H6O7P2Na2
Structural Formula:
Properties:
HEDP•Na2 is an organophosphorus acid corrosion inhibitor that can chelate with Fe, Cu, and Zn ions, providing excellent scale and corrosion inhibition effects even under temperatures such as 250℃. It demonstrates excellent stability even under elevated pH levels and has good tolerance for acidic/alkaline solutions and chlorine oxidation. It is not easily hydrolyzed or decomposed under normal light and heat conditions. Additionally, it forms six-ring chelating compounds with metal ions in the water system, particularly Ca2+, and has good scale inhibition effects as well as dissolution threshold effects. Furthermore, when combined with other Water Treatment Chemicals, the synergistic results are further enhanced.
