EDTA-4Na Disodium Salt Chelating Agent for Water Treatment
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".
Aliases
Ethylenediaminetetraacetic Acid Tetrasodium Salt
English Name
Tetrasodium EDTA
Chemical Formula
C₁₀H₁₂N₂Na₄O₈
Molecular Weight
380.16
CAS Number
64-02-8
Key Properties
Powerful chelation
High water solubility
Broad pH adaptability
Excellent thermal stability
