Other Specification : Detergent C2H8O7P2, HEDP Acid 60% Min CAS 2809-21-4, HEDPA, HEDP(A), Etidronic Acid For Metal And Nonmetal Model Number: TY2002-2 Chemical Name: 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid Abbreviation: HEDP Synonym: HEDPA, HEDP(A), Etidronic Acid CAS No.: 2809-21-4 Dequest: 2010 Molecular Formula: C2H8O7P2 Molecular Weight: 206.02 G/mol Structural Formula: Applications: HEDP Can Chelate With Fe, Cu, And Zn Ions To Form Stable Chelating Compounds. It Shows Excellent Scale And Corrosion Inhibition Effects Under Temperature 250. HEDP Has Good Chemical Stability Under High PH Value, Hard To Be Hydrolyzed, And Hard To Be Decomposed Under Ordinary Light And Heat Conditions. So HEDP Is Normally 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 Detergent 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 Detergent. Usually, HEDP Is Used Together With Polycarboxylic Acid.
