Basic information
Disodium EDTA, also known as EDTA-2Na, is a good chemical agent. The chemical formula is C10H14N2Na2O8, molecular weight is 336.206, it has six coordination atoms, the formation of complexes called chelates, EDTA in coordination titration is often used to determine the content of metal ions. EDTA has important applications in industries such as dyes, foods, and pharmaceuticals.
Disodium edetate is tasteless, odorless or slightly salty white or Milky White crystalline or granular powder, odorless, tasteless. It is soluble in water and extremely difficult to dissolve in ethanol. It is an important chelating agent that chelates metal ions in solution. To prevent the discoloration, deterioration, turbidity and oxidation loss of vitamin C caused by metals, but also to improve the antioxidant properties of oils and fats (trace metals such as iron and copper in oils and fats have the effect of promoting the oxidation of oils and fats).
Application areas
Main purpose:
For heavy metal antidote, complexing agent, antioxidant synergist, stabilizer and softener; calcium, magnesium and other metal reagents, metal masking agent. Disodium EDTA is an important complexing agent for complexing metal ions and separating metals.
Packaging, transportation and safety
Operation Precautions:
Closed operation, strengthen ventilation. Operators must be specially trained and strictly abide by the operating procedures. Operators are advised to wear self-priming filter dust masks, chemical safety goggles, anti-poison penetration overalls and rubber gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid creating dust. Avoid contact with oxidizing agents. Handle and unload lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances.
Storage Precautions:
Store in a cool, ventilated warehouse. Keep away from fire and heat source. Should be stored separately from the oxidant, do not mix storage. Equipped with the corresponding variety and quantity of fire fighting equipment. The storage area shall be provided with suitable materials to contain spills.
Transport notes:
The package shall be complete at the time of shipment and the loading shall be safe. During transportation, ensure that the container does not leak, collapse, fall or damage. It is strictly prohibited to mix with oxidants, edible chemicals, etc. During transportation, it shall be protected from sun exposure, rain and high temperature. The vehicles shall be thoroughly cleaned after transportation.
