Versuchsvorschrift

4-Cyano-2,3,5,6-tetrachlorobenzamide (284 g) which had been synthesized separately and water (2556 g) were placed in a four-neck flask, and the mixture was cooled to 15° C. with stirring. Subsequently, an aqueous solution (2360 g) of sodium hypochlorite (effective chlorine 12%) was added to the reaction mixture over six hours while a 50% aqueous solution of sulfuric acid was added so as to maintain the pH of the mixture at 5-6. Liquid chromatographic analysis revealed that the reaction mixture contained 262.2 g of 4-cyano-2,3,5,6-tetrachlorobenzoic acid (yield 92%).
