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.
