1-Hydroxyethylidene-1,1-diphosphonic acid factory

Hydroxyethyl ethyl diazeptic acid (INN), 1-hydroxyethane 1, 1-diphosphonic acid (HEDP), also known as HEDP, is a diphosphate compound used in deterging sperm, water purification processes, cosmetics and pharmaceutical production.
The salt produced by this acid is chemically MnHEDP (M is a cation, n is the number of M, up to 4).

quality
Hydroxyethyl fork diazepine is white crystallization. Melting point 198 to 199 degrees C. Soluble in water, soluble in methanol, ethanol. When heated to high temperatures, it breaks down slowly, releasing dangerous gases. Industrial products are colorless to pale yellow transparent liquid, harmful.
preparation
Hydroxyacetamic acid can be obtained by the reaction of acetylchloride with phosphoric acid.
use
In the electroplating industry, it is used as a universal complex agent for cyanide-free plating. Circulating cooling water system, used as the main agent of water quality stabilizer, is an organic polysacid acid, with corrosion resistance effect.
