PROCESS FOR THE PRODUCTION OF AROMATIC TRIFLUOROMETHYL COMPOUNDS OF THE BENZENE SERIES Abstract of the Disclosure An improved process for the production of aromatic trifluoromethyl compounds of the benzene series by con- version of the corresponding trichloromethyl compound with hydrogen fluoride. The aromatic trichloromethyl compound of the benzene series is converted in the presence of antimony pentachloride, which is a catalyst, in a quantity, related to the quantity of the trichloromethyl compound, of 200 to 700 ppm per trichloromethyl group in the trichloromethyl compound, with a stoichiometric quantity, or at most a 2 percent excess, of hydrogen fluoride. The conversion is conducted at a pressure of 20 to 45 atm., at a temperature of 60 to 75°C. and with intermixing which is characterized by a Reynolds number between 50,000 and 80,000. Yields of around 98 percent are achieved.
