反応手順
206 parts of 3,5-dichloroanthranilic acid are introduced into 200 parts of isopropanol and 800 parts of 18 percent strength by weight hydrochloric acid. A solution of 100 parts of NaNO2 in 140 parts of water are run in at 80° C., resulting in the uniform evolution of nitrogen. The mixture is cooled, 500 parts of water are added and the product is filtered off. 182 parts (95% of theory) of 3,5-dichlorobenzoic acid of melting point 178°-180° C. are obtained.
