Product Introduction

Tetrasodium EDTA is a highly efficient water-soluble polydentate chelating agent, renowned for its robust metal ion binding capacity, exceptional chemical stability, and broad pH applicability. Its production primarily relies on the condensation reaction of ethylenediamine and sodium chloroacetate, with the mainstream process being the synthesis under alkaline conditions via "ethylenediamine + sodium chloroacetate → Tetrasodium EDTA + sodium chloride".
