Introduction of Antioxidation Agent EDTA-2Na
It occurs as white crystalline particle or whiteto gray white crystalline powder, odorless and tasteless. It absorbs moisture slightly. It’s easily soluble in water andalmost insoluble in ethanol. PH of 5% aqueous solution is 4-6. Its’ complex capacity is very strong. It reacts with heavy metal ions to form stable soluble complex compound so as to remove these heavy metal ions or the harmful effects caused by them.
Application
- used as chelate agent, preservative, antioxidant and processing additive
- Mainly used in adhesives, filament winding, laminates, high performance coatings and tank liner coatings, as a curing agent for epoxy resins and chain extenders for polyurethanes.
- Use for heavy metal quantitative analysis agent; used to complex iron ions, control polymerization rate
- Uses Complexing agents, calcium, magnesium and other metal reagents, metal masking agents. Disodium edetate is an important complexing agent for complexing metal ions and separating metals.
Features of Disodium Edetate Dihydrate(Edta-2na)
Among the salts of ethylenediaminetetraacetic acid, the disodium salt is the most important and is an important complexing agent for complexing metal ions and separating metals. It can also be used in detergents, liquid soaps, shampoos, and agricultural chemical sprays. The agent, the color photosensitive material, the bleaching fixer, the water purifying agent, the pH adjusting agent, the cation agent, and the like. In the redox initiation system for styrene-butadiene rubber polymerization, disodium EDTA is used as a component of the active agent to mainly complex ferrous ions and control the polymerization rate. This product is low in toxicity, and the oral LD50 of rats is 2000 mg/kg.
Packing & Storage
