반응 단계
137 parts of 2-aminobenzoic acid are introduced into 800 parts of ethanol, 50 parts of hydrochloric acid (20% strength of weight) and 500 parts of water. 163 parts of chlorine gas are passed in over 2 hours at 80° C. 300 parts of hydrochloric acid (36 percent strength by weight) are added. 125 parts of isopropyl nitrite are introduced in the course of 7 hours at 80° C. The mixture is cooled, 800 parts of water are added and the product is filtered off. 143 parts of 3,5-dichlorobenzoic acid (75% of theory) of melting point 173°-178° C. are obtained.
