Application

Ethylenediaminetetraacetic acid (EDTA) is an important complexing agent. EDTA has a wide range of applications and can be used as a bleaching and fixing agent for color sensitive material processing, dyeing aid, fiber treatment aid, cosmetic additive, blood anticoagulant, detergent, stabilizer, synthetic rubber polymerization initiator. EDTA is a representative substance of chelating agents. It can form stable water-soluble complexes with alkali metals, rare earth elements, and transition metals. In addition to sodium salts, there are also ammonium salts and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum, etc. These salts have different uses. In addition, EDTA can also be used to detoxify harmful radioactive metals by rapidly excreting them from the human body. It is also a water treatment agent. EDTA is still an important indicator, but it is used to titrate metals such as nickel and copper. When used, it must be used together with ammonia to act as an indicator.

EDTA is an excellent chelating agent for calcium and magnesium ions. It is used as a chelating agent for water used in lotion polymerization to remove Ca2+, Mg2+, Fe2+, Fe3+and other metal ions. It is also used as a complexing agent for anaerobic adhesives, that is, EDTA is used to treat methacrylate diesters, remove transition metal ions, and eliminate the effects that can promote peroxide decomposition, which has a very good effect on improving the stability of anaerobic adhesives. EDTA sodium salt chelating metal ions can improve the speed of modified acrylic acid. Storage stability of Solid Structure Adhesive (SGA), dosage -3 × 10-4-6.0 × 10-4. The dosage is 1.5%, and the storage stability at 50~C reaches over 360 hours (stored at 50 ℃ for 4 days, equivalent to 1 year of SGA20~C storage).

Commonly used for softening boiler water quality. Preventing scaling
