Preparation method of 4-amino-2-trifluoromethyl benzonitrile

The invention relates to the technical field of chemical engineering, in particular to a preparation method of 4-amino-2-trifluoromethyl benzonitrile, which comprises the following steps: after 2-bromo-5-fluorobenzotrifluoride is subjected to a Grignard reaction, feeding carbon dioxide, and hydrolyzing to obtain 4-fluoro-2-trifluoromethyl benzoic acid; adding the 4-fluoro-2-trifluoromethyl benzoicacid into a pressure kettle, feeding liquid ammonia, and reacting under the action of a catalyst to generate 4-amino-2-trifluoromethyl benzamide; heating and dehydrating the 4-amino-2-trifluoromethylbenzamide with a dehydrating agent to generate the 4-amino-2-trifluoromethyl benzonitrile. According to the preparation method, highly toxic cuprous cyanide is not adopted, so that the safety risk ofproduction is reduced, and three wastes do not contain cyanide ions or a large amount of copper ions, are easier to treat and have small harm to the environment.
