Disodium ethylenediaminetetraacetic acid, also known as EDTA-2Na, is a good coordination agent in chemistry. The chemical formula is C10H14N2Na2O8, with a molecular weight of 336.206. It has six coordination atoms and forms a complex called a chelate. EDTA is often used in coordination titration to determine the content of metal ions. EDTA has important applications in industries such as dyes and food.
Disodium ethylenediaminetetraacetic acid is a odorless or slightly salty white or milky white crystalline or granular powder, odorless and tasteless. It is soluble in water but extremely difficult to dissolve in ethanol. It is an important chelating agent that can chelate metal ions in solution. Preventing discoloration, deterioration, turbidity, and oxidation loss of vitamin C caused by metals can also improve the antioxidant properties of fats (trace metals such as iron and copper in fats can promote lipid oxidation).
1. EDTA has extensive coordination properties and can form stable chelates with almost all metal ions. Advantages: It provides the possibility of widely determining elements (better than acid-base and precipitation methods). Disadvantage: Multiple components can easily interfere with each other - selectivity.
2. The coordination ratio between EDTA and the formed M-EDTA is mostly 1:1.
3. Most chelates are charged, so they can dissolve in water and react quickly. Toxicity protection: This product is low in toxicity. The oral LD50 for rats is 2000mg/kg. Packaging: Packed in double layer plastic bags lined with cardboard boxes or jute bags, each weighing 80kg. Physical and chemical properties: White crystalline powder. Low toxicity, soluble in water, with a pH value of 4-6 in a 5% aqueous solution. It is acidic. Difficult to dissolve in alcohol. Mainly used as a complexing agent.
Application
Used as a complexing agent, antioxidant synergist, stabilizer, and softener; Calcium, magnesium, and other metal reagents, metal masking agents. Disodium ethylenediaminetetraacetic acid is an important complexing agent used for complexing metal ions and separating metals.
Packaging and Transportation
Packing: In 25kgs/ bag.
Storage: Keep container tightly closed in a cool, dry and well-ventilated place, avoiding exposure of the packaged product to direct sunlight.
