      Used as a pharmaceutical intermediate. Used in the production of the broad-spectrum intestinal anthelmintic mebendazole. Production method: It is obtained by condensing o-dichlorobenzene with benzoyl chloride. Mix o-dichlorobenzene, benzoyl chloride, and anhydrous aluminum chloride, stir, heat, and react at 130-135°C for 4 hours. After cooling slightly, place in 3% chemical-free hydrochloric acid, filter, and wash with water until neutral to obtain crude 3,4-dichlorobenzophenone. Decolorize the crude product by reflux with 6% ethanol, 0.05% activated carbon, and 0.25% hydrochloric acid for 30 minutes. Filter while hot. Cool the filtrate to below 10°C, filter, and dry to obtain the finished product. Yield: 71%.
