Disodium Of 1 Hydroxy Ethylidene Diphosphonic Acid Hedp Na - China

Monosodium of 1-Hydroxy Ethylidene-1, 1-DiphosphonicAcid (HEDP•Na)

CAS No.

29329-71-3

Molecular Formula: C2H7O7P2Na Molecular weight: 228

Structural Formula:

Properties:

HEDP•Na is an organophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, and Zn ions.

HEDP•Na can dissolve the oxidized materials, it has good scale and corrosion inhibition effects even under 250C, it 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•Na can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular.

HEDP•Na has good scale inhibition effects and obvious dissolution threshold effects.

When used with other Water Treatment Chemicals, the synergistic effects is better.

HEDP•Na is suitable for acidic scale inhibitor and detergent, can be used for metal surface treatment.
