Disodium EDTA, also known as EDTA-2Na, is a good compounding agent in chemistry. It has six coordination atoms, and the complex formed is called chelate. EDTA is often used in coordination titration, generally to determine the content of metal ions. EDTA has important uses in dye, food and other industries.
Application:
  1. EDTA has antioxidant properties and a strong chelating effect on metal ions, making it a stabilizer. Our country stipulates that it can be used for Pickled vegetables and canned food, and the maximum use amount is 0.25g/kg.
  2. Among the salts of EDTA, disodium salt is the most important. EDTA disodium salt is an important complexing agent for complexing metal ions and separating gold chemobooks. It can also be used in detergents, liquid soaps, shampoo, agricultural chemical sprays, color sensitive materials, bleaching fixatives, water purification agents, pH regulators, anion coagulants, etc.
  3. EDTA mainly used in adhesives, fiber winding, laminates, high-performance coatings, and tank lining coatings, as a curing agent for epoxy resins and a chain extender for polyurethane monome.
