CAS No. 7651-99-2
Molecular Formula: C6H15O12N2P4Na5
Molecular weight: 546.13
EDTMP•Na5 is a neutral
product. It is nitrogenous organic polyphosphonic acid,
which is a part of cathodic corrosion inhibitor.
can be fully dissolved in water, innocuous and none
pollution to environment, has good chemical stability and
EDTMP•Na5 has good scale
inhibition property under temperature 200℃.
EDTMP•Na5 can dissociate into 8 positive-negative ions,
thus can chelate with more than two metal ions to form more
than two polymer reticulation complex, the complex can be
quickly dissolved in water to destroy the normal
crystallization of calcium scale.
EDTMP•Na5 shows better scale
inhibition effects to calcium sulfate and barium sulfate.
can be used as scale and corrosion inhibitor for circulating
water and boiler water system, chelating agent in
non-cyanide electroplating, water-softening agent in dyeing
