Audited Supplier EDTA disodium salt (anhydrous), also known as EDTA-2Na, is a good compound in chemistry. Chemical formula C10H14N2Na2O8, molecular weight 336.206, it has six coordination atoms, the formation of the complex called chelate, EDTA is often used in coordination titration, generally to determine the content of metal ions. EDTA has important applications in dyes, food, medicine and other industries.
Edta disodium is odorless or salty white or milky white crystalline or granular powder, odorless and tasteless. It is soluble in water and extremely insoluble in ethanol. It is an important chelating agent that can chelate metal ions in solution. Prevent discoloration, deterioration, turbidity and oxidation loss of vitamin C caused by metal, and also improve the oxidation resistance of oil (trace metals in oil such as iron, copper, etc., can promote the oxidation of oil).
Use
Among the salts of EDTA, disodium salt is the most important. It is an important complexing agent. Used in electroless copper plating, gold plating, lead-tin alloy plating, electrochemical polishing of steel parts and solution before copper silver plating, EDTA-Na can also be used instead. Also used in detergents, liquid soap, shampoo, agricultural chemical sprays, color sensitive materials washing processing bleaching fixing solution, water purification agent, PH regulator, coagulant and so on. In the reduction initiation system of styrene butadiene rubber polymerization, disodium EDTA, as a component of the active agent, is mainly used to complex ferrous ions and control the polymerization rate.
