CAS No. 2809-21-4
Molecular Formula: C2H8O7P2
Molecular weight: 206.02
HEDP is an organophosphorus 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 shows the excellent scale and corrosion inhibition effects under temperatures of 250℃. HEDP has good chemical stability under high PH values, is hard to be hydrolyzed, and is hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphorus acids (salt).HEDPcan react with metal ions in the water system to form hexa-element chelating complex, with calcium ions in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.

HEDP is used as scale and corrosion inhibition in circulating cool water systems, oil fields, and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.
In the light woven industry, HEDPis used as a detergent for metal and nonmetal. In the dyeing industry, HEDP is used as a peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating,
HEDPis are used as a chelating agent. The dosage of 1-10mg/L is preferred as a scale inhibitor, 10-50mg/L as a corrosion inhibitor, and 1000-2000mg/L as a detergent. Usually, HEDP is used
together with polycarboxylic acid.
Package
HEDP liquid: 200L plastic drum, IBC(1000L), customers' requirement.
HEDP solid: 25kg/bag, customers' requirement.
Storage for ten months in a room shady and dry place.
