METHOD FOR OBTAINING VANILLIN FROM AQUEOUS BASIC COMPOSITIONS CONTAINING VANILLIN

摘要

The invention relates to a method for obtaining vanillin from an aqueous, basic composition containing vanillin, in particular from a composition produced in the oxidation, especially in the oxidation by means of electrolysis, of aqueous alkaline compositions containing lignin, comprising at least one treatment of an aqueous, basic composition containing vanillin, in particular the treatment of a composition produced in the oxidation, especially in the oxidation by means of electrolysis, of aqueous alkaline compositions containing lignin, with a basic adsorbent, in particular an anion exchanger
