CAS No.: 7651-99-2
Molecular Formula: C6H15O12N2P4Na5
Molecular weight: 409
is a neutral solid product. It is nitrogenous organic polyphosphonic
acid, which is a part of cathodic corrosion inhibitor. EDTMP•Na5
can be fully dissolved in water, innocuous and none pollution to
environment, has good chemical stability and thermal tolerance.
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
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 industry, etc.
solid state EDTMP•Na5 is slightly easy to deliquescence, convenient
in transportation and suitable for usage in winter and freezing
