摘要： PURPOSE:To obtain the subject compound useful as an intermediate raw material for pharmaceuticals, agrichemicals and information recording materials with simple process in high yield by reacting pentafluorobenzofc acid with ammonia in an aqueous medium. CONSTITUTION:Pentafluorobenzoic acid is made to react with ammonia in an aqueous medium at 40-230 deg.C. After the reaction, the reaction solution is separated into an oily layer and an aqueous layer by distillation, etc., and the objective 2,3,5,6-tetrafluoroaniline is separated from the oily layer. The aqueous layer is reused in the reaction. The amount of ammonia is 2-60mol based on 1mol of pentafluorobenzoic acid. Pentafluorobenzoic acid can be produced by the hydrolysis of pentafluorobenzonitrile in an aqueous solution of sulfuric acid.
