반응 단계
206 parts of 3,5-dichloroanthranilic acid are introduced into 500 parts of 45 percent strength by weight sulfuric acid and 400 parts of isopropanol. A solution of 100 parts of sodium nitrite in 140 parts of water is run in over 5 hours at 80° C.; nitrogen is evolved. The mixture is cooled, 1,000 parts of water are added and the product is filtered off. 172 parts (90% of theory) of 3,5-dichlorobenzoic acid of melting point 175°-178° C. are obtained.
