Product Description
EDTMPS
CAS No.: 22036-77-7 EINECS NO.: 244-742-5
Molecular Formula: C6H12O12N2P4Na8
CAS No.: 22036-77-7 EINECS NO.: 244-742-5
Molecular Formula: C6H12O12N2P4Na8
Molecular Weight: 612.13
Properties:
EDTMPS is a nitrogen-containing organic polybasic phosphonic acid, and belongs to cathodic corrosion inhibitors. Compared with inorganic polyphosphate, its corrosion rate is 3~5 times better than them. EDTMPS can be fully dissolved in water, innocuous and has none pollution to environment, with good chemical stability and thermal tolerance. EDTMPS shows excellent scale inhibition ability under temperature 200ºC. EDTMPS can dissociate into 8 positive-negative ions in aqueous solution, thus can chelate with many metal ions to form a plurality of single-structure macromolecular reticulation complex, loosely dispersed in water, and destroy the normal crystallization of calcium scale.
