What is EDTA?

EDTA is an aminopolycarboxylic acid, short for Ethylenediaminetetraacetic acid, with the chemical formula [CH2N (CH2CO2H) 2] 2. It is in the 'poly' carboxylic group due to the presence of more than one bonded -COOH group in its structure. It is also in the 'amino' group due to the -NH2 bond to its structure. This white, water-soluble solid acid is commonly used to bind to iron and calcium ions. EDTA binds the ions as a hexadentate (“hexadentate”) chelator. EDTA, especially disodium EDTA; It is produced as some salt types such as sodium calcium edetate and tetrasodium EDTA. It is a type of acid used in molecular biology applications.

There are other names used to refer to EDTA. These are the long version of ethylenediamine tetraacetic acid, as we mentioned first; chelating agent, chelating agent; 60-00-4; Na2 and Na4.

How is EDTA Produced?

Both single and two-step synthesis can be used in the production of EDTA. In the two-stage synthesis production of EDTA, the EDTA salt was contaminated with the NTA salt. In the single-stage synthesis EDTA production, there is no separation process. Although the setup and equipment costs are lower in single-stage production, higher purity EDTA production is possible after two-stage production.

The production of EDTA for industrial use is formaldehyde containing cyanide; It is made by reaction and synthesis with compounds such as ethylenediamine, HCN & NaCN. After the formation of the sodium salt of EDTA, sulfuric acid and hydrochloric acid are used to acidify this salt.

What does the EDTA look like?

It is colorless and crystalline solid.

What is the chemical formula of EDTA?

Molecular formula: C10H16N2HE8

In which areas is EDTA used?

  • Textile sector
  • Pulp and paper manufacturing industry
  • As a preservative in the Food Industry
  • Soft Drink Industry
  • Medicine and Medical Medicine
  • Pharmaceutical Industry
  • Cosmetics Industry
  • Water purification industry in cleaning

What are EDTA processes?

  • In industry, EDTA is mainly used to keep metal ions in aqueous solution.
  • In the textile industry, it prevents metal ion impurities from changing the colors of dyed products.
  • In the pulp and paper industry, EDTA inhibits the ability of metal ions, particularly Mn2+, to catalyze the disproportionation of hydrogen peroxide used in chlorine-free bleaching.
  • EDTA is added to some foods as a preservative or stabilizer to prevent catalytic oxidative discoloration catalyzed by metal ions.
  • In soft drinks containing ascorbic acid and sodium benzoate, EDTA reduces the formation of benzene (carcinogen).
  • In laundry applications, both EDTA and similar complex substances are used to reduce water hardness, dissolve limescale in boilers, and bind Ca2+, Mg2+ and other metal ions. After binding to EDTA, these metal centers affect the non-precipitation or action of soaps and detergents. This is why cleaning solutions often contain EDTA.
  • EDTA is used for the determination of free lime and free magnesium in cement and clinkers in the cement industry, similar to the cleaning industry.
  • EDTA is used for cleaning machines in oil production facilities.
  • It is used for the removal of sulfur fumes from the chimney in waste washing plants and coal production plants.
  • Sodium calcium edetate, an EDTA derivative, is used to bind metal ions in the treatment application after mercury and lead poisoning. It is used similarly to remove excess iron from the body. This therapy is used to treat thalassemia as well as to treat the complication of repeated blood transfusions.
  • Dentists and endodontists use EDTA solutions to remove inorganic residues (smear layer) and lubricate root canals in endodontics. This procedure helps prepare root canals. In addition, surfactant-added EDTA solutions loosen calcifications within a root canal and allow canal shaping.
  • In addition, EDTA can be used as a preservative in eye drops.
  • It is useful in medicine for the assessment of kidney function, especially for assessing the glomerular filtration rate (GFR).
  • EDTA is widely used in blood analysis. EDTA is an anticoagulant that chelates the calcium present in the blood sample, stopping the clotting process and preserving blood cell morphology.
  • In addition, EDTA was found to be quite effective in inhibiting the proliferation of bacteria during the implantation of intraocular lenses.
  • EDTA salts are used in shampoos, cleansers and other personal care products as a release agent to increase their stability in air.
