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.

EDTA-2Na is a white crystalline powder in appearance, it is odorless, tasteless, soluble in water, and extremely difficult to dissolve in ethanol. In industry, it is mainly used as a chelating agent, and also as a heavy metal detoxifier, complexing agent, antioxidant synergist, stabilizer and softener, etc.; as an anticoagulant in blood collection tube additives. When in use, EDTA-2Na is generally configured as a solution, so various problems will inevitably be encountered in these configuration solutions. Let's take everyone to understand how to solve these problems.
How does EDTA-2Na dissolve? What to do if it is insoluble?
It can be dissolved at room temperature, but the speed is very slow. EDTA has a low solubility in water and is only soluble in alkaline, so NaOH should be added.
Can EDTA-2Na be dissolved by heating?
EDTA-2Na uses water as the solvent and is stirred and dissolved at about 90C. Generally, there will be no chemical changes. It can be dissolved in boiling water at 160C and slightly soluble in cold water. EDTA can be dissolved in sodium hydroxide, sodium carbonate and ammonia solution, and neutralization reaction will occur. It is insoluble in alcohol and general organic solvents. It can chelate with calcium and magnesium ions. The melting point is greater than 220C and will decompose.
How to dissolve EDTA-2Na completely?
The solubility of EDTA-2Na in water is about 110g/L. It dissolves slowly at room temperature. Heating can accelerate the dissolution, and it will not precipitate when cooled after dissolution.
Is EDTA-2Na sticking to the skin harmful during operation?
In fact, our EDTA-2Na can adjust the pH of cosmetics in skin care products, that is, it can automatically adjust the pH of cosmetics within the range that we can fit, so as to protect our skin from strong irritation. Therefore, in a certain amount of circumstances, it plays a role in protecting the skin, so you don't have to worry too much about getting it on your hands accidentally during the experiment. Just rinse it with water.
