Bo Ruite Zhejiang nitrilotriacetic acid trisodium NTA trisodium factory price

Trisodium nitrilotriacetic acid (NTA trisodium) Chinese name: Nitrilotriacetic acid trisodium salt Synonyms: N, N'- bis (carboxymethyl) glycine trisodium salt; nitrilotriacetic acid trisodium; nitrilotriacetic acid trisodium; nitrite triacetates, sodium; nitrilotriacetic acid sodium salt Formula: C6H6NNa3O6 Molecular Weight: 257.08 CAS Number: 5064-31-3 Test items Standard Index Content% ≥99.0 PH value of 10.50-11.50% 5% aqueous transparent chloride (cl meter ) ≤0.02 Sulfate% (in terms of SO4) ≤0.02% iron content (calculated as Fe) ≤0.01 Packing: 25kg / bag or according to customer requirements for packaging. Storage: Store in dry and ventilated warehouse, avoid direct sunlight, light stack gently. Characters: the white crystalline powder. Boiling point 167 ℃ (13 mm Hg), heated to ≥246 ??℃ decomposed to produce carbon monoxide, carbon dioxide, and nitrogen oxides are toxic fumes. Dissolved ammonia and alkaline solutions, water-soluble and insoluble in organic solvents. Strong oxidants, aluminum, copper, copper alloy and nickel can not coexist. It can provide four metal ion coordination bonds, and it has smaller molecules, so that it has very strong complexing ability with various metal ions to form stable chelates. Nitrilotriacetic acid (NTA) has a strong biological decomposition. According to reports, NTA decomposed by the bacteria test, the final product is CO2 and NH3. Test showed: NTA in the river, at a temperature of 2 ℃, the decomposition rate of 82-88 after two weeks, a few weeks after fully biodegradable. Purpose: The main purpose is as follows: 1. It is all cooked Fan complexing agents complexing agents, can be used with a variety of metal forming metal complexes, analyzed and measured, and separation of rare metals. It can also be used to extract the individual metals from rare. 2. The catalyst in the production of polyurethane foams, which can be used as blowing catalyst, foaming can be immediately and quickly gelled. 3. stabilizer in polystyrene production, it can be used as a stabilizer. The detergent in the anti-nuclear steam generator system heap, which can be used as an aqueous solution injection of steam - water cycle to remove dirt and corrosive substances intramural, in the accession process without sacrificing efficiency. 5. plating agent in a non-toxic plating, which can speed up the deposition rate. 6. The color photographic developer in color photographic developing, and it is one of the important ingredients that can be used to prevent precipitation of developing production. Nitrilotriacetic acid as tripolyphosphate substitutes, in the presence of synthetic detergent resolved so that the problem of eutrophication also received attention in addition to the above uses, as well as for the following purposes: 1. For the foamed polyurethane foam The catalyst for this purpose in recent years in the use of new uses foreign NTA can immediately foaming gel quickly, use large, it is very promising. 2. The rare earth elements used for washing. 3. to growth inhibitors rice, barley, tomatoes and other crops, can regulate the growth of crops, and adjust its harvest. The higher fatty ammonium salt of nitrilotriacetic acid can inhibit bacterial and fungal growth. 5. nitrilotriacetic acid formulated deodorant, deodorization rate of 92.2% NH3, to MeSH, Me3N, H2S, indole-3-methyl indole deodorization rate of 90.3%, 88.9% and 89.4%, respectively, 81.6% and 80.0%. 6. Printing inks and other industrial production nitrilotriacetic acid slurry was added, the viscosity can be adjusted. As the stabilizer, NTA can be added to the metal anti-corrosion coatings, paper waterproof coatings, pesticides, chemicals, diacetone alcohol and other chemicals, and can make increased stability of the product.
