- REACTION OF PERFLUORINATED METHYL- AND ALKENYLBENZENES WITH INORGANIC OXIDES IN THE PRESENCE OF ANTIMONY PENTAFLUORIDE
-
A study was carried out on the reaction of perfluorinated toluene, m-xylene, p-xylene, mesitylene, and m-(1-propenyl)toluene with inorganic oxides in the presence of antimony pentafluoride.Depending on the reaction conditions, polyfluorinated acids resulting from the consecutive conversion of trifluoromethyl groups into carboxylic acid groups are obtained after hydrolysis of the reaction mixtures.

- Process for the preparation of 2,3,5,6-tetrafluorobenzoic acid, and the new compounds 2,3,5,6-tetrachloro-4-trifluoromethyl-benzoyl chloride and 2,3,5,6-tetrafluoro-4-trifluoromethyl-benzoyl fluoride
-
2,3,5,6-Tetrafluorobenzoic acid is prepared from 4-trifluoromethyl-benzoyl fluoride by chlorination, fluorination, hydrolysis, decarboxylation and saponification. The new compounds 2,3,5,6-tetrachloro-4-trifluoromethyl-benzoyl chloride and 2,3,5,6-tetrafluoro-4-trifluoromethyl-benzoyl fluoride are produced during this as intermediates.
