1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP)
[CAS] 2809-21-4 Dequest:2010
Molecular Formula: C2H8O7P2 Molecular weight: 206
Structural Formula:

Properties:
This product is an organophosphoric acid corrosion inhibitor, It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds, thus it can dissolve the oxidized materials on these metals’ surfaces. HEDP shows excellent antiscale corrosion inhibition effects under temperature 250℃. It has good stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions.
Usage:
This product is widely used in circulating cool water system, oil field water pipelines and low-pressure boilers for antiscale corrosion inhibition in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light weaven industry, this product is used as detergent for metal and nonmetal. In dyeing industry, this product is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, this product is used as chelating agent.
