Cas No. :1429-50-1
Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium(EDTMPS)
CAS No. 1429-50-1 Molecular formula: C6H12O12N2P4Na8 Molecular weight: 612.13 Structural formula 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 can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. It shows excellent scale inhibition ability under temperature 200℃. 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 sulfate. Specification Items Index Appearance Clear yellow to umber transparent liquid Active component (EDTMPS)% 30.0min Organic phosphonic acid (as PO43-)% 10.0min Phosphorous acid(as PO33-)% 5.0max Phosphoric acid (as PO43-)% 1.0max Chloride (Cl-) % 3.0max pH (1% water solution) 9.5-10.5 Density (20℃)g/cm3 1.25min Usage 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. Package and storage 200L plastic drum,IBC(1000L),customers’ requirement. Storage for ten months in shady room and dry place.
