Ethylenediaminetetraacetic Acid Disodium Salt
Synonyms：Trilon BD; Dissolvine NA2; EDTA 2NA
Molecular Formula：C10H14N2Na2O8
CAS RN.：6381-92-6
UN NO.: N/A
Ethylenediamine tetraacetic acid disodium, also known as EDTA-2Na, is a good compound in chemistry. The chemical formula is C10H14N2Na2O8, and the molecular weight is 336.206. It has six coordination atoms, and the complex formed is called chelate. EDTA is often used in coordination titration, which is generally used to determine the content of metal ions. EDTA has important uses in dye, food, medicine and other industries.
Application
Industrial grade use of EDTA 2NA
① Industry: clean up heavy metal ions and Ca2+ and Mg2+ ions.
② Soap: combine with Ca2+ and Mg2+ ions in hard water to reduce hardness.
③ Photography: Fe(III)EDTA was used as oxidant.
④ Textiles: combined with heavy metals.
⑤ Oil production: EDTA is added to prevent mineral precipitation.
⑥ Milk: wash the milk bottle.
⑦ Nitrogen oxides: exhaust gas treatment.
Food grade use of EDTA 2NA
The purity of food grade EDTA must be above 99%. It is a widely approved food additive (such as FDA). It is an antioxidant and quality improver, and has functions of preventing oil oxidation, food Browning and emulsifying food.
① Food: as an antioxidant, its role is to chelate metal ions to avoid the oxidation of oil.
Cosmetics: add EDTA to preserve cosmetics.
③ Soda: EDTA can avoid the carcinogenic benzene produced by soda containing ascorbic acid and sodium benzoate.
Water test: test the hardness of water.
Medical grade use of EDTA 2NA
Medical-grade EDTA can be used as an antidote to heavy metal poisoning because of its purity. In addition, the addition of EDTA to blood samples can avoid agglutination during delivery.
① Mercury toxicity treatment: Use EDTA disodium calcium salt – ethylenediamine tetraacetic acid disodium calcium (EDTA Na2-Ca) to treat heavy metal poisoning. It treats people with mercury poisoning, it treats people with lead poisoning. By virtue of its ability to bind heavy metals, EDTA generates stable and soluble salts, which are excreted in urine.
② Laboratory medicine: as an anticoagulant for blood and other liquid samples (such as blood samples used for complete blood count).
③ Dentistry: used to remove some organic or inorganic substances during root canal therapy.
④ Biochemistry: EDTA is used in molecular biology to prevent the influence of metal ions on enzymes.
