Abstract: The present invention relates to a process for producing vanillin from an aqueous, basic vanillin-comprising composition, in particular from a composition as arises in the oxidation, especially in the oxidation by electrolysis, of aqueous alkaline lignin-comprising compositions, comprising at least one treatment of an aqueous, basic vanillin-comprising composition, in particular the treatment of a composition as arises in the oxidation, especially in the oxidation by electrolysis, of aqueous alkaline lignin-comprising compositions, with a basic adsorbent, in particular an anion exchanger.
