Etidronic Acid
CAS No. 2809-21-4
Alias: ETHANE-1-HYDROXY-1,1-DIPHOSPHONIC ACID, 95+%;(1-Hydroxyethylidene)biphosphonic acid;Hydroxyethylidene Diphosphonic acid (HEDP);
Molecular formula：C2H8O7P2
Molecular weight：206.03
Structural formula：
1.Performance and use:
Pure product is white crystal. Industrial product is colourless to light yellow transparent liquid. Soluble in water, soluble in methanol and ethanol. Hydroxyethylidene Diphosphonic Acid is a chemical raw material often used in industrial water treatment, household cleaning products and personal care products.
This product is the main material for cyanide-free electroplating. It is formulated into cyanide-free copper plating solution, and the copper layer is plated directly on sodium iron with good bonding. The plating layer is smooth and has good colour. The general dosage of 60% content is 100-120mChemicalbookl/L. The dosage of copper sulphate is 15-20g/L. In addition, before plating, dip the plated parts in 1%-2% solution of this product, so that the plated parts will turn into the activated state, and then plating can improve the effect.
Hydroxyethylidene diphosphonic acid (HEDP) is a new type of non-chlorine electroplating complexing agent, used as the main agent for water quality stabilisation in circulating cooling water system, and plays the role of corrosion and scale inhibition. This product is one of the organic polyphosphonic acid water tablets, domestic production of such products and other varieties, such as amino-trimethylene phosphonic acid (ATMP): [CH2PO (OH) 2] 3N and ethylenediamine tetramethylene phosphate (EDTMP) and so on. Organic polyphosphonic acid is a class of water treatment agents developed in the late 1960s and confirmed around the 1970s, and the emergence of this type of treatment agent has made a big step forward in water tablet technology Chemicalbook. Compared with organic polyphosphates, organic polyphosphonic acid has a good drug aunt's chemical stability, not easy to hydrolyse, can withstand higher temperatures and drug dose is small and both slow and etching scale performance and other characteristics. It is a class of cathodic corrosion inhibitor, and a class of non-chemical equivalent scale inhibitor; and other water treatment agents used in combination, showing ideal synergistic effect. Many metal ions such as calcium, magnesium, copper, zinc, etc. have excellent chelating ability, and even the inorganic salts of these metals, such as CaSO4, CaCO3, MgSiO3, etc. also have good de-activation, and therefore a large number of applications in water treatment technology.
