Property:

EDTA appears as white crystal powder. EDTA can be soluble in sodium hydroxide, sodium carbonate and ammonia solution.EDTA is not soluble in cold water, acid and common organic solvents and discomposed at 240°C.

Usage and Application:

EDTA Mainly applied to complexing metal ions, and separating metal. EDTA can be used as water-treating agents and scale-eliminating agents. EDTA is capable of preventing the harmful effects on production caused by metal ions in water. EDTA is also used in cleaning the boilers in large-scale power plants.White crystal powder, soluble in sodium hydroxide, sodium carbonate and ammonia solution, not soluble in cold water, acid and common organic solvents,and discomposed at 240°C. Also used in the  dyeing adjuvant, processing agent for fibers, cosmetic additive, etc.

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.
