1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP)
CAS No. 2809-21-4
Molecular Formula: C2H8O7P2 Molecular weight: 206.02
Alias: Hydroxyethylidene Diphosphonic Acid
Properties and Applications
An organic phosphonic acid scale/corrosion inhibitor. Chelates metal ions (Fe, Cu, Zn), dissolves metal oxides. Effective up to 250°C, stable at high pH, resistant to hydrolysis and decomposition. Good chemical/chlorine resistance compared to other phosphonates. Forms stable chelates with Ca²⁺, providing scale inhibition and a threshold effect. Synergistic with other water treatment agents.
- Solid is high-purity, suitable for cold climates; also for electronics cleaning and daily chemicals.
- Used for scale/corrosion inhibition in cooling water, low/medium pressure boilers, oilfield water injection, and pipelines. Also used in textiles as a cleaner, peroxide stabilizer, dye fixative, non-cyanide electroplating complexing agent, and radioactive element carrier in pharmaceuticals.
