Ethylenediaminetetraacetic acid CAS: 60-00-4
Product introduction
Ethylenediaminetetraacetic acid CAS: 60-00-4
chemical properties
This product crystallizes out from water as white powder. The solubility in water at 25℃ is 0.5g/L. Insoluble in cold water, alcohol and general organic solvents. Soluble in sodium hydroxide, sodium carbonate and ammonia solutions.
Production method:
Reaction of ethylenediamine and chloroacetic acid. Add 100kg of chloroacetic acid, 100kg of ice and 135kg of sodium hydroxide solution (30%) into the reaction kettle, and then add 18kg of 83% to 84% ethylenediamine under stirring. Incubate at 15°C for 1 hour. Add 30Chemicalbook% sodium hydroxide solution in batches of 10L each time. After each addition, add another batch after the phenolphthalein test solution does not show red. Keep at room temperature for 12h. Heat to 90°C and decolorize with activated carbon. Filter, wash the filter residue with water, and finally adjust the pH value to 3 with concentrated hydrochloric acid. Cool and crystallize, filter and wash with water until there is no chloride ion reaction. Dried products.
Reaction of ethylenediamine with formaldehyde and sodium cyanide. Mix 60% ethylenediamine aqueous solution, 30% sodium cyanide aqueous solution and sodium hydroxide, and keep the mixture at 20°C for 0.5h. Then add formaldehyde aqueous solution dropwise. After the reaction, the chemicalbook was decompressed and the water was evaporated. Then repeat the above operation, adding excess formaldehyde for the last time to allow the sodium cyanide to react completely. Adjust pH to 1.2 with dilute acid. A white precipitate precipitated, filtered, washed with water, and dried at 110°C. Get the product.
Application field
Ethylenediaminetetraacetic acid (EDTA) is an important complexing agent. EDTA is widely used and can be used as bleaching fixative in the processing of color photosensitive materials, dyeing auxiliaries, fiber processing auxiliaries, cosmetic additives, blood anticoagulants, detergents, stabilizers, synthetic rubber polymerization initiators, EDTA is a chelate Representative substances of mixtures. It can form stable water-soluble chemical 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, and aluminum. Each of these salts has different uses. In addition, EDTA can also be used to quickly excrete harmful radioactive metals from the human body and play a detoxifying role. It is also a water treatment agent. EDTA is also an important indicator, but it is used to titrate metal nickel, copper, etc. When used, it must be used together with ammonia to function as an indicator.
