Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (EDTMPS)

CAS No. ********1 Synonym: Dequest ***0

Molecular Formula: C6H*2O*2N2P4Na8 Molecular weight: **2.*3

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.
EDTMPS shows excellent scale inhibition ability under temperature **0ƒ. It dissociates 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. It has better antiscale effects to calcium sulfate and barium sulfate.

Specification:

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~*0mg/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:
**0L plastic drum, IBC (***0L), customers requirement.
Storage for ten months in shady room and dry place.
