Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (EDTMPS)
CAS No. 1429-50-1 
Equivalent of Dequest 2040
Molecular Formula: C6H12O12N2P4Na8 Molecular weight: 612.13


EC / List no.: 215-851-5
CAS no.: 1429-50-1
Mol. formula: C6H20N2O12P4

Structural Formula:
NCH2CH2CH2Na2O3PNa2O3PCH2NCH2CH2PO3Na2PO3Na2

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. 
EDTMPS can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. 
EDTMPS shows excellent scale inhibition ability under temperature 200℃. 
EDTMPS 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.

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:
Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.
