Storage method
This product should be sealed and stored in a cool, dry place.
Synthesis method
Dissolve 60g chloroacetic acid in 200ml water, neutralize with 25g potassium carbonate, add 15g ethanolamine and 40g potassium carbonate, heat and reflux for 3 hours, cool and acidify to pH=2 with concentrated hydrochloric acid. After cooling, hydroxyethyl imine diacetic acid crystals precipitate. After recrystallization with water, 22g of finished product was obtained with a yield of 50%.
Purpose
