実験手順: 480 g (1.83 mols) of 2,3,4-trichloro-5-fluorobenzoyl chloride are introduced, with 240 g (12 mols) of hydrogen fluoride, at -5° to 0° C. into a stirred autoclave fitted with a pressure-control valve, the apparatus is pressure-sealed and warmed to 70° C. in steps, corresponding to the evolution of HCl. The hydrogen chloride produced is continuously released at 4-5 bar. When the evolution of HCl is complete, the mixture is cooled, the excess pressure is released and the reaction mixture is fractionated. fitted with a pressure-control valve the apparatus is pressure-sealed

実験手順: 737 g (3.02 mols) of 2,3,4-trichloro-5-fluorobenzoic acid are introduced into 1.5 liters of thionyl chloride at room temperature, and the mixture is refluxed for 16 hours until the gas evolution ceases. Excess thionyl chloride is removed by distillation, and the residue is distilled. the mixture is refluxed for 16 hours until the gas evolution ceases Excess thionyl chloride is removed by distillation the residue is distilled
