EDTA is a white powder under normal temperature and pressure. It can be dissolved in sodium hydroxide, sodium carbonate and ammonia solutions, soluble in boiling water, slightly soluble in cold water, and insoluble in alcohol and general organic solvents. In order to better use it, let's follow the potassium hydroxide manufacturer to fully understand the characteristics and product uses of EDTA.
Characteristics of EDTA
EDTA is an important complexing agent. EDTA has a wide range of uses. It can be used as bleaching fixative, dyeing agent, fiber processing agent, cosmetic additive, blood anticoagulant, detergent, stabilizer, synthetic rubber polymerization initiator for the washing and processing of color sensitive materials.
EDTA is a representative substance of chelating agent, which can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salt, there are also ammonium salt and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt and aluminum, which have different uses.
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 metal ions such as ca2+, mg2+, fe2+, fe3+. It is also used as a complexing agent for anaerobic glue, that is, EDTA is used to treat the double ester of methacrylate, remove the transition metal ions, and eliminate the influence that can promote the decomposition of peroxides, which has a very good effect on improving the stability of anaerobic glue.
Application in water treatment:
EDTA has a wide range of coordination ability, can form stable chelates with almost all metal ions, and its metal chelates have good solubility under slightly acidic conditions, so it has long been used as an inhibitor of harmful metal ions and a softener of water in the textile industry. Due to the good water solubility of its metal ion chelates, more and more researches and applications have been made in the cleaning of water equipment.
Application in agriculture:
The Cu, CA, Fe, Mg, Zn and other metal salts of EDTA series chelating agents have the advantages of good solubility and easy absorption, and become a good source of micronutrient fertilizers. Moreover, these chelated metal salts do not affect their solubility after mixing with each other, which is conducive to the use as multi-element composite micronutrient fertilizers. In addition, EDTA has carboxyl groups participating in the reaction, which can generate potassium salts and ammonia salts, and supplement potassium fertilizer and nitrogen fertilizer while supplementing trace elements. Considering the cost and effect comprehensively, it will be the first choice of chelated micronutrient fertilizer for a long time, so it will be applied more and more widely in China.
EDTA series chelating agents are also widely used in photography, textile, printing and dyeing, papermaking, daily chemicals and chemical analysis. In addition, it should be stored in a cool and ventilated warehouse and sealed. During transportation, it shall be protected from sun exposure, rain and high temperature.
