EDTMP Pentasodium Salt CAS 7651-99-2

Introduction

EDTMP Pentasodium Salt is a nitrogen-containing organic polyphosphonic acid, a cathodic corrosion inhibitor. Compared with inorganic polyphosphates, its corrosion inhibition rate is 3 to 5 times higher. It is miscible with water, non-toxic and non-polluting, with good chemical stability and temperature resistance, and still has a good scale inhibition effect at 200°C.
EDTMP Pentasodium Salt can dissociate into 8 positive and negative ions in aqueous solution, so it can chelate with multiple metal ions to form multiple monomer structure macromolecular network complexes, which are loosely dispersed in water, destroying the normal crystallization of calcium scale.
EDTMP Pentasodium Salt has a good scale inhibition effect on calcium sulfate and barium sulfate scale.
Specification

Application:

EDTMP Pentasodium Salt is used as a corrosion and scale inhibitor for circulating water and boiler water, a chelating agent for cyanide-free electroplating, a chelating agent in the textile printing and dyeing industry, and an oxygen bleaching stabilizer.
