CAS:1429-50-1 Molecular Formula: C6H12O12N2P4Na8C Molecular weight: 612.13 1, Properties EDTMPS is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor. Its corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. It is miscible with water, innocuous and none pollution to environment, has good chemical stability and temperature tolerance. It shows excellent scale inhibition ability under temperature 200oC. It can dissociate into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. EDTMPS shows better antiscale effects to calcium sulfate and barium. 2, Specification: Items Index Appearance Clear yellow to umber transparent liquid Active component (as EDTMPS)% ¡Ý 30.0 Organic phosphonic acid(asPO43- )% ¡Ý 10.0 Phosphorous acid (as PO33- )%¡Ü 5.0 Phosphoric acid (asPO43- )%¡Ü 1.0 pH (1% water solution) 9.5-10.5 Density (20oC) g/cm3¡Ý 1.25 Chloride (as Cl-)%¡Ü 3.0. 3,Application range&using method:EDTMPS can be used as corrosion inhibitor in circulating cool water system and boiler water. It is a chelating agent in non-cyanogen electroplating industry and a water-softening agent in printing & dyeing industry. When used alone, 2~10mg/L is preferred. When built with HPMA by ratio ETDMP:HPMA=1:3, it can be used for low pressure boiler. It can also be built with BTA, PAAS and zinc salt.Organic phosphonic acid Package and Storage:Normally EDTMPS packed with 25kg net Plastic Drum, or packed as customer¡¯s required. Storage for ten months in room shady and dry place.
Ethylene Diamine Tetra (Methylene Phosphonic Acid) EDTMPA (Solid) CAS No 1429-50-1 Dequest: 2040 Molecular Formula: C6H20 N2O12P4 Molecular weight: 436.13 Structural Formula: Properties: EDTMPA is white crystal powder at room temperature, with melting point 215-217íµ, hard to be dissolved in water, the solubility is less that 5% at room temperature, easy dissolved in ammonia. EDTMPA has strong metal ion chelating capacity, whose chelating constant with cuprum ion is larger than that of EDTA. EDTMPA has high capacity for chelating metal ions. The complex constant with Cu is the largest in all chelating agents including EDTA. EDTMPA is a kind of high-pure grade reagent and innocuous, it can be used as detergent in semiconductor chip to prepare integrated circuit, as carrying agent for radioelement in medical industry, and as agent for inspection and therapy. The chelating capacity of EDTMPA largely exceed that of EDTA and DTPA, and can replace EDTA for chelating agent at almost any situation.

EDTA 2 Sodium EDTA 4 sodium, Magnesium Series
Tetrasodium EDTA is an amino acidic chelating agent minimizing metal ion contamination and facilitating enzymatic reactions that could be inhibited by heavy metal traces. EDTA Tetrasodium salt also works as a slime dispersant and is even effective in reducing scale deposits and water hardness.
Edtmps is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor.Its corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. It can be fully dissolved in water, innocuous and none pollution to Normally in 250kg net plastic drum, ibc drum can also be used as required.
