structural formula of hedp (2809-21-4):

properties of hedp (2809-21-4):
hedp (2809-21-4) is an organophosphoric acid corrosion inhibitor. it can chelate with fe, cu, and zn ions to form stable chelating compounds. it can dissolve the oxidized materials on these metals' surfaces. hedp (2809-21-4) shows excellent scale and corrosion inhibition effects under temperature 250°c. hedp (2809-21-4) has good chemical stability under high ph value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). hedp (2809-21-4) can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. therefore, hedp (2809-21-4) has good antiscale and visible threshold effects. when built together with other water treatment chemicals, it shows good synergistic effects.

specification of hedp (2809-21-4):

appearance	colorless to light yellow transparent liquid
active content (hedp)%	58.0-62.0
phosphorous acid (as po33-)%	1.0 max
phosphoric acid (aspo43- )%	0.5 max
chloride (as cl-)%	0.3 max
ph (1% solution)	2 max
density (20°c)g/cm3	1.40 min

usage of hedp (2809-21-4):

1. hedp (2809-21-4) is used as scale and corrosion inhibition in circulating cool water system, oil fieldand low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc..

2. in light woven industry, hedp (2809-21-4) is used as detergent for metal and nonmetal.

3. in dyeing industry, hedp (2809-21-4) is used as peroxide stabilizer and dye-fixing agent.

4. in non-cyanide electroplating, hedp (2809-21-4) is used as chelating agent. the dosage of 1-10mg/lis preferred as scale inhibitor, 10-50mg/l as corrosion inhibitor, and 1000-2000mg/l as detergent.

usually, hedp (2809-21-4) is used together with polycarboxylic acid.

package and storage of hedp (2809-21-4):
hedp (2809-21-4): normally in 250kg net plastic drum, ibc drum can also be used as required.

storage for ten months in shady room and dry place.
