1,2-Cyclohexanedinitrilotetraacetic acid | [Flammability and Explosibility]
Notclassified | [Synthesis]
Weighed 1.04g of trans-1,2-cyclohexanediamine sulfate product and 2.31g of chloroacetic acid, dissolved in 2.5mL of distilled water. Under the condition of room temperature, add NaOH aqueous solution (5.0mL, 30%) dropwise while stirring, after the drop | [Purification Methods]
Dissolve CDTA in aqueous NaOH as its disodium salt, then precipitate it by adding HCl. The free acid is filtered off and boiled with distilled water to remove traces of HCl [Bond & Jones Trans Faraday Soc 55 1310 1959]. Recrystallise it from water and dry it in vacuo.[Beilstein 13 III 10.] |
