Uses

1,2-Cyclohexanedinitrilotetraacetic acid

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.]
