Abstract: A method of purifying a stream having an aromatic carboxy-aldehyde and an aromatic acid or the corresponding anhydride is described. The method includes reacting a hydroxylamine-containing compound with the aromatic carboxy-aldehyde in the stream to form a reaction mixture including the corresponding nitrone; adding an aqueous solvent to the reaction mixture, in an amount and under conditions effective to solubilize the nitrone but not the organic acid or the corresponding anhydride; and separating the solubilized nitrone from the non-solubilized organic acid. The nitrone is a water soluble nitrone.
