Product Description
CAS No. 1429-50-1
Molecular Formula:C6H12O12N2P4Na8
Molecular weight: 612.13
Structural Formula:
Properties:
EDTMPS is a nitrogenous organic polyphosphoric acid and a potent cathodic corrosion inhibitor that can be dissolved in water, making it innocuous and non-polluting. This chemical has exceptional stability and tolerance to thermal conditions, displaying potent scale inhibition under temperatures of up to 200℃. Furthermore, EDTMPS can dissociate into 8 positive-negative ions, which it uses to chelate with multiple metal ions forming polymer reticulation complexes that disrupt the normal crystallization of calcium scale. Additionally, this acid has efficacy over calcium and barium sulfate, providing more efficient antiscalant effects than conventional inorganic polyphosphates.
