1-Hydroxyethylendiphosphonic Acid CAS No.2809-21-4 Purity: 60% & 90% Synonyms: HEDP Molecular Formula:C2H807P2 Formula Weight:206.03 Package:250kg/Plastic drum, 25kg/bag Product Description: 1.HEDP is an organophosphoric acid corrosion inhibitor.It can chelate with Fe, Cu, and Zn etc. metal ions and form stable complex compound.It can dissolve the oxidized materials on these metals'surfaces.Under 250'C HEDP shows excellent scale and corrosion inhibition ability. 2. HEDP has good chemical stability under high pH value, hard to be hydro-lyzed,and hard to be decomposed under ordinary light and heat conditions. lts acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). 3. HEDP can react with metal ions in water system to form hexa-element chelating complex. with calcium ion in particular.Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects. 4. The solid of HEDP is high purity product, suitable for using in winter and freezing districts.It is quite suitable for using as cleaning agent in electronic fields and as additives in daily chemicals. Application Range: 1. HEDP is widely used in the in circulating cool water system of electric power, chemical industy, metallurgy, fertilizer, etc.and widely used as a scale and corrosion inhibitor of low-pressure boilers, field waterflood, oil pipeline 2. In light&textile industry, HEDP is used as detergent for metal and nonmetal.In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent. 3. In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor,and 1000-2000mg/L as detergent. Usually,HEDP is used together with polycarboxylic acid. Packing and storage: Store above 0â??/32â?? .Do not use steel containers. Suitable containers include polyethylene,fibreglass,glasslined steel and polyvinyl chloride.Do not use copper or brass plumbing or valves.Ensure tha containers,whether empty ,or full or part full,are tightly sealed unless in use.Avoid creating or breathing product mist.

Specification: 1.Eco-friendly, high effective 2.For water treatment 3.Prompt Delivery 4.ISO/SGS Technical Data: Items Specification Appearance Colorless or yellowish transparent liquid Assay 50% min Ph value 3-5 Color 80 max Recently, certain companies have mixed formaldehyde (low price) into glutaraldehyde (high price). such irresponsible behavior has disordered the market. As a leading supplier in this line, We guarantee that all our glutaraldehyde products are free of formaldehyde. Product Description: 1.Glutaraldehyde is colorless or yellowish clear and bright liquid with slight irritating smell, and can be dissolved in organic dissolvent such as water, ether and ethanol. 2.In water solution, Glutaraldehyde doesn't exist much in free state; instead, Glutaraldehyde makes appearance as hydrates with different forms, and most of them are hydrates with annular structure. 3.Glutaraldehyde is reactive in property, and liable to polymerize and oxidize, which will react with compounds containing active oxygen and nitrogen. The reaction of the product with protein is mainly carried out between the carbonyl group of the former and the amino group of the latter. Among the known aldehydes, the product is one of the best cross-linking agents for proteins. 4.Glutaraldehyde has a small influence on the activity of enzyme, and most of enzymes can be fixed under controlled condition, to cross-link without losing their activity. Contributing to its outstanding characteristics, the product has drawn special concern from people and been put at broad application.
