What is NTA ACID CAS 139-13-9?

Nitrilotriacetic acid, abbreviated as NTA, CAS 139-13-9. Nitrilotriacetic acid is a typical amino polycarboxylic acid chelating agent. Due to the presence of multiple coordination groups in its molecular structure, nitrilotriacetic acid can form stable chelates with metal ions and is widely used in industries such as manufacturing, environmental protection, and daily chemicals.

Pure nitrilotriacetic acid is a white crystalline powder or needle-like crystals with no distinct odor. Industrial products may be slightly yellowish powder due to differences in purity and are prone to moisture absorption (they need to be stored in a sealed container).

Application

1. Nitrilotriacetic Acid is a well-known complexing agent, which can form metal complexes with various metals, analyze and measure, and separate rare metals. It can also be used to extract individual metals from rare metals.

2. Catalyst In the production of polyurethane foam, nitrilotriacetic acid can be used as a foaming catalyst, which can foam and gel quickly.

3. Stabilizer In the production of polystyrene, nitrilotriacetic acid can be used as a stabilizer.

4. Detergent In the steam generator system of the nuclear reactor, nitrilotriacetic acid NTA can be injected into the steam-water cycle as an aqueous solution to remove the scale and corrosive substances between the walls, and the efficiency will not be affected during the addition process.

5. Electroplating agent In non-toxic electroplating, nitrilotriacetic acid NTA can speed up the deposition rate.

6. Color photographic developer In color photographic development, nitrilotriacetic acid NTA is one of the important components, which can be used to prevent the formation of precipitation during development.

7. Nitrotriacetic acid is a substitute for tripolyphosphate, and nitrilotriacetic acid has also received attention in solving the problem of eutrophication of water in synthetic detergents.
