Products Description
Introduction:
Ethylenediaminetetraacetic acid is an organic compound with a chemical formula of C10H16N2O8 and a white powder at room temperature and pressure. It is a chelating agent that can be combined with two valence metal ions such as Mg2+, Ca2+, Mn2+ and Fe2+. Because most nucleases and some proteases require Mg2+, they are often used as inhibitors of nuclease and protease, and they can also be used to remove the inhibitory effect of heavy metal ions on enzymes.

Main Application:
Ethylenediaminetetraacetic acid purpose
1, EDTA is an important complexing agent. EDTA is widely used as bleaching fixative, dyeing auxiliaries, fiber treatment auxiliaries, cosmetic additives, blood anticoagulants, detergents, stabilizers, synthetic rubber polymerization initiator, EDTA is a representative chelating agent. It can form stable water soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salt, there are ammonium salt and iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum and other salts, these salts have different uses. In addition, EDTA can also be used to detoxify harmful radioactive metals from human body. It is also a water treatment agent. EDTA is also an important indicator, but used to titrate nickel, copper, etc., when used with ammonia in order to play an indicator role.
2. EDTA is an excellent chelating agent for calcium and magnesium ions. It is used as a chelating agent for water emulsion polymerization to remove metal ions such as Ca2+, Mg2+, Fe2+ and Fe3+. It can also be used as a complexing agent for anaerobic adhesives, that is, EDTA is used to treat dimethyl methacrylate to remove transition metal ions and to eliminate the effect of promoting the decomposition of peroxides, which is very good for improving the stability of anaerobic adhesives. EDTA sodium chelate metal ions can improve the speed of modified acrylic acid. The storage stability of solid structural adhesive (SGA) is -3 * 10-4 to 6 * 10-4. The storage stability of 50~C was more than 360h at 1.5%, and stored at 50 C for 4D, equivalent to SGA20~C storage for 1 years.
3, commonly used in boiler water softening. Prevent scaling.
