Wholesale food additive disodium edetate

Disodium edetate also called EDTA-2Na EDTA-2Na formula, EDTA-2Na molecular weight, English name: EDTA-2Na (EDTA Disodium Salt), molecular formula: C10H14N2Na2O8 2H2O, molecular weight:? 372.24, CAS: 6381- with HOOCH2C CH2COONa N-CH2-CH2-N HOOCH2C CH2COONa disodium edetate also called EDTA-2Na, is a good fit in the chemical agent, which has six coordinating atoms, form: 92-6 formula substance called chelate, EDTA titration often used in coordination, in general, is determination of metal ions. Appearance: white crystalline powder. Odorless. Soluble in water. Main purpose: chelating agent, preservative, antioxidant synergists, processing aids. This product is used as a color photographic materials Processing bleach fixing solution, and dyeing auxiliaries, fiber treatment agents, cosmetic additives, blood anticoagulant, complexing agents, detergents, stabilizers, synthetic rubber, a polymerization initiator and quantification of heavy metals Analysis agent. In that the reduction of benzene chlorination rubber polymerization initiator system, EDTA-2Na as an integral part of the active agents, mainly used for complexing iron ions, to control the polymerization reaction rate. 1, EDTA has a broad ligand properties, almost all of the metal ions to form stable chelates advantageous place: offers the possibility of measuring a wide range of elements (superior acid, precipitation) disadvantages: Multiple Easy interference between components - Selective 2, EDTA and M- EDTA ligand formation than most of 1: 13, chelate most charged, it can dissolve in water, rapid response.
