English description（英文原文，共 1312 字符）
Product Name:Disodium EDTA
English Name:Disodium EDTA
CAS No.:139-33-3
Aliases:Disodium ethylenediaminetetraacetate, EDTA disodium salt, Sodium edetate
Molecular Formula:C10H14N2Na2O8
Physical Properties:White crystalline granules or white powder, odorless; soluble in water, slightly soluble in ethanol, insoluble in ether and benzene; chemically stable, resistant to acids, alkalis and hard water; rapidly combines with calcium, magnesium, iron, copper and other metal ions to form stable soluble complexes.
Uses:Widely used as a high-efficiency chelating agent, complexing agent and stabilizer. In water treatment, it is used for water purification and heavy metal removal; in daily chemical and detergent industries, it acts as a hard water softener and detergency enhancer; in textile dyeing and printing, it chelates metal ions to prevent color spots and shade differences. It is also applied in electroplating complexing, food preservation, pharmaceutical excipients and cosmetic formulations, with low addition levels and broad process compatibility.
Technical Specifications:
Assay (as C10H14N2Na2O8): ≥99.0%
Product grades: industrial, daily chemical and food grade, all premium quality
pH of 5% aqueous solution: 4.0–6.0
Chelating value (as CaCO3): ≥100 mg/g
Water insoluble matter: ≤0.01%
