  • Publication number: 20210040030
    Abstract: Method of purifying an alkali metal salt of a compound of the general Formula (I) or Formula (II) wherein R1, R2 and R3 are independently H, an alkyl, an alkenyl, or a hydroxyalkyl radical containing from 1 to 18 carbon atoms, or from 1 to 6 carbon atoms; or wherein R1 and R2 form jointly together with the N atom a heterocyclic 5- or 6-membered ring; said method comprising providing a mixture comprising said, an alkali metal hydroxide and water, and subjecting the mixture to a step (X): (X) reducing the quantity of removing said alkali metal hydroxide from the mixture; wherein (A) said alkali metal hydroxide is reduced by subjecting said mixture to electrodialysis; and/or (B) said alkali metal hydroxide is reduced by adding an acid to said mixture.
