What is 1-Hydroxyethylidene-1,1-Diphosphonic Acid?
Hydroxyethylidene diphosphonic acid (etidronic acid (INN), 1-hydroxyethane 1,1-diphosphonic acid (HEDP), international non-proprietary drug name), also known as HEDP, is a detergent, water purification process, Bisphosphonate compounds in the production of cosmetics and pharmaceuticals.
The salt produced by this acid has the formula MnHEDP (M is the cation and n is the number of M, up to 4).
HEDP is a natural phosphonic acid scale and rust prevention, which can develop secure facilities with iron, copper, zinc as well as various other metal ions, as well as can liquify oxides on the metal surface area. It can still play an excellent function in corrosion and also scale restraint at 250 ° C, and also it is still very steady at high pH, challenging to be hydrolyzed, and challenging to decay under basic light and heat problems. Acid and alkali resistance as well as chlorine oxidation resistance are better than various other natural phosphonic acids (salts). It can form six-ring chelates with metal ions in water, especially calcium ions, so it has good scale restraint effect and apparent solubility restriction effect. When made use of in mix with other water tr eatment agents , it reveals a perfect collaborating result.
1-Hydroxyethylidene-1,1-Diphosphonic Acid Uses
Phosphorylation reagent for protected serines and pyranoses.
This product is the main product of cyanide-free electroplating. It is prepared as a cyanide-free electroplating copper remedy, and the straight electroplating copper layer on sodium iron has good bonding pressure. The finish is smooth and the shade is great. The general dose of 60% is 100-120ml/ L. The dose of copper sulfate is 15-20g/ L. On top of that, prior to electroplating, immerse the plated components in the 1% to 2% solution of this item to make the electroplated components develop into a turned on state, and then electroplating can improve the impact.

Application of 1-Hydroxyethylidene-1,1-Diphosphonic Acid
Hydroxyethylidene diphosphonic acid (HEDP) is a brand-new sort of chlorine-free electroplating complexing representative, which is made use of as the major agent for water top quality security in the flowing cooling water supply, and also plays the function of deterioration as well as scale inhibition. This item is among the natural multi-phosphonic acid-free water-sheeting representatives. There are various other sorts of such items generated in China, such as aminotrimethylenephosphonic acid (ATMP): [CH2PO(OH)2] 3N and B Diamine tetramethylene phosphate (EDTMP), and so on. Organic polyphosphonic acid is a type of water therapy representative developed in the late 1960s and also verified around the 1970s. The appearance of this sort of therapy representative has actually made water sheeting technology a big progression. Compared to natural polyphosphate, organic polyphosphonic acid has the qualities of excellent chemical security, hard to hydrolyze, heat resistance, tiny dose, as well as anti-corrosion performance. It is a type of cathodic rust prevention and a type of non-chemical comparable range prevention; when utilized in mix with other water treatment agents, it reveals an ideal synergistic effect. It has outstanding chelating capacity for many metal ions such as calcium, magnesium, copper, zinc, etc, and also has a great deactivation impact on not natural salts of these steels such as CaSO4, CaCO3, MgSiO3, and so on, so it is widely made use of in water treatment innovation.
Preparation of 1-Hydroxyethylidene-1,1-Diphosphonic Acid
In the industry, glacial acetic acid as well as phosphorus trichloride are typically made use of for futures, and then the condensation technique of the acylated product as well as the hydrolyzate of phosphorus trichloride is made use of. Add metered water and glacial acetic acid into the reaction pot and stir uniformly. Phosphorus trichloride was added dropwise under cooling, and also the response temperature level was controlled at 40-80 ° C. The by-product hydrogen chloride gas is condensed and sent out to the absorption tower to recuperate hydrochloric acid. Splashed acetyl chloride as well as acetic acid are condensed as well as returned to the activator. After going down phosphorus trichloride, raise the temperature to 100-130 ° C, and also reflux for 4-5 hrs. After the reaction is over, it is hydrolyzed with steam, as well as the recurring acetic acid as well as low boiling point compounds are evaporated. obtain the item.
