Product Name:Trisodium Nitrilotriacetate
English Name:Trisodium Nitrilotriacetate
CAS No.:5064-31-3
Aliases:Nitrilotriacetic acid trisodium salt, NTA trisodium salt, Trisodium N,N-bis(carboxymethyl)glycinate, Nitrogen triacetic acid trisodium salt
Molecular Formula:C6H6NNa3O6
Physical Properties:White crystalline powder; molecular weight 257.08; melting point approximately 320°C (decomposition); freely soluble in water, aqueous solution is alkaline; stable in air, decomposes at high temperatures; almost insoluble in ethanol and ether; EINECS No. 205-355-7.
Uses:Used as a chelating and complexing agent, mainly for metal ion extraction, coordination reactions, and catalyst preparation. In the dye industry, it serves as a fixing agent to enhance the affinity between dyes and fibers, reducing color fading. It acts as a stabilizer in styrene production and as a catalyst and complexing agent in polyurethane foam production, helping to regulate foaming speed and cell structure.
Technical Specifications:
Purity ≥99%
Melting point: approx. 320°C (decomposition)
Solubility: freely soluble in water, forming an alkaline solution
Packaging: 25 kg/bag, lined with plastic film and outer woven bag
Storage: keep in a cool, dry, well-ventilated warehouse, sealed and away from high temperature
