Structural Formula of HEDP (2809-21-4):
Properties of HEDP (2809-21-4):
HEDP (2809-21-4) is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. It can dissolve the oxidized materials on these metals' surfaces. HEDP (2809-21-4) shows excellent scale and corrosion inhibition effects under temperature 250°C. HEDP (2809-21-4) has good chemical stability under high PH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). HEDP (2809-21-4) can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP (2809-21-4) has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.

Usage of HEDP (2809-21-4):
1. HEDP (2809-21-4) is used as scale and corrosion inhibition in circulating cool water system, oil fieldand low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc..
2. In light woven industry, HEDP (2809-21-4) is used as detergent for metal and nonmetal.
3. In dyeing industry, HEDP (2809-21-4) is used as peroxide stabilizer and dye-fixing agent.
4. In non-cyanide electroplating, HEDP (2809-21-4) is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent.
Usually, HEDP (2809-21-4) is used together with polycarboxylic acid.
Package and Storage of HEDP (2809-21-4):
HEDP (2809-21-4): Normally in 250kg net Plastic Drum, IBC Drum can also be used as required.
Storage for ten months in shady room and dry place.
