Picture Example:

EDTA 2NA is white crystalline powder, soluble in water, almost insoluble in ethanol, ether, its aqueous solution pH is about 4-5.Disodium EDTA, also known as edta-2na, is a good complexing agent in chemistry. It has six coordination atoms, forming a complexcalled chelate. Pure EDTA 2NA is an important kind of complexing agent.

Product Feature of EDTA 4Na 2Na

1.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°C, it shows the tendency to depart from carboxyl.
2.Melting point: 240°C(decomposition)
3.Dissolving degree in water: 0.5g/L(25°C)

Function of EDTA 4Na 2Na

Paper-making

EDTA is used for treating the steamed fiber. It will promote the whiteness of paper and reduce the incrustation in the steamer.

Pharmaceutical industry

Through cyclopolymerization with methyl amide, EDTA is made into ethyl amide, a remedy for psoriasis.

Textile dyeing and printing

EDTA 4Na 2Na will promote color ability of the dyestuff and brightness of the dyed fabric.
