1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP) C2H8O7P2
CAS NO.:2809-21-4
SYNONYMS: Dequest 2010, Etidronic Acid
HEDP is a cost effective scale inhibitor used in various industrial applications such as industrial water treatment and ***ergents. It further shows good stability in presence of chlorine as well as corrosion inhibition properties in presence of zinc and other phosphates. HEDP can be also used as chelating agent in the textile industry.
Applications:
Cooling water systems / industrial water treatment
Industrial ***ergents
Swimming pools
Metal surface treatment as corrosion inhibitor for steel
Stabilizer in H2O2 solutions
Sequestering agent in textile auxiliaries
Usage:
HEDP?is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry,?HEDP?is used as ***ergent for metal and nonmetal. In dyeing industry,?HEDP?is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating,?HEDP?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 ***ergent. Usually,?HEDP?is used together with polycarboxylic acid.
