Feature：EDTA is a white crystal powder，insoluble in common organic solvents，soluble in boiling water 160 times as much and in alkali solvents like sodium hydroxide. At 150℃, it shows the tendency to depart from carboxyl. Melting point： 240℃(decomposition) Dissolving degree in water： 0.5g/L(25℃)

Quality Specification： 　　　　　　　　　　 Appearance： White Crystal Powder 　　　　　　　　　　 Assay%：≥99.0 　　　　　　　　　　 Test on Dissolving in Sodium Carbonate Solution：Pass 　　　　　　　　　　 Residue after Burning (Sulfate) 　%：≤0.15 　　　　　　　　　　 Chloride( Cl- )　：≤0.01 　　　　　　　　　　 Sulfate(SO42-)　%：≤0.1 　　　　　　　　　　 Iron (Fe) %≤ : 0.001 　　　　　　　　　　 Heavy Metal (Pb) %≤ : 0.001

Main Application：An agent for complexation, EDTA is mainly used for water treatment, as an additive to detergent, a chemical for photography, paper-making and oil-field.

It is also used as detergent for boiler cleaning and reagent in chemical analysis. 　　　　　　　 1． High molecular chemical industry: EDTA is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre production. 　　　　　　　 2．Daily chemicals: EDTA is used as additive to detergent, skin cream and hair-conditioner. 　　　　　　　 3．Paper-making: EDTA is used for treating the steamed fibre.

It will promote the whiteness of paper and reduce the incrustation in the steamer. 　　　　　　　 4．Pharmaceutical industry: Through cyclopolymerization with methyl amide, EDTA is made into ethyl amide, a remedy for psoriasis.

It is also a stablizer for some vaccines and an antihaemoagglutinin. 　　　　　　　 5． Textile dyeing and printing: EDTA will promote colour ability of the dyestuff and brightness of the dyed fabric.
