HEDP or Etidronic Acid or Hydroxyethylidene phosphonic acid is a corrosion inhibitor. The Molecular Formula is C2H8O7P2. It combines with Fe, Cu, and Zn ions and chelates those to form stable chelating compounds.it can melt the metal oxide of the metal surface as well. It has two states, solid like white crystal powder and liquid-like colorless to yellowish acidic liquid. aluminum sulfate is a similar product to this chemical.
HEDP in solid type is crystal powder. Due to its high purity, it is decent for usage in winter and freezing areas.it has the best functional under temperature 250centigrade degree.it is stable in high PH.it hydrolyzed and decompose sorely under ordinary light and heat conditions.
chemical properties of Etidronic Acid:
In the table below some of the chemical properties of this product are mentioned. All data that is mentioned in this table is gathered from the Wikipedia website:
HEDP INDUSTRIAL USE:
Furthermore, this component is used in several industrial applications such as anti-corrosion and anti-deposition in the circus system, in the basis of petroleum; low-Pressure Boilers, and in the metallurgy industry. this component is an essential element in cosmetic formulation for oppressing organizing free radicals, stabilize the emulsion, and control viscosity.it is functional in the Cosmetic industry, water refinery and Detergent .it is utilized in the middle of chemical materials in the swimming pool as an inhibitor.it keeps the color-blending sides of the pool. HEDP Na2 use in cool water flow, medium boiler, water pipelines, and Corrosion inhibitors in the field of electricity, chemical industry, manure and etc. HEDP Na2 use as a detergent for metal and non-metal. In the Dyeing industry, HEDP Na2 use as a peroxide Stabilizer and coloring agent. In Nano cyanide plating, HEDP Na2 use as a Chalet factor. In spite of the above, the most used of this compound is in the water purification and water treatment area.
PRODUCTION:
It is created by reaction Phosphorus dichloride with acetic acid or by reaction acetic acid/ stearic anhydride with Phosphoric acid. STORAGE: It can save for 10 months in the shade and dry room.
GLOBAL MARKETING HEDP :
All in all, this product is ascendant in the global market. The main reason for growth this matter in the global market is the high rate of the township, increase in revenue of consumers and the negative point of it is the undesirable effects of it such as weaken the body, skin problems, bone pain and etc.
