- POTASSIUM FLUORIDE DISPERSION SOLUTION, AND PROCESS FOR PRODUCTION OF FLUORINATED ORGANIC COMPOUND USING THE SAME
-
A potassium fluoride dispersion essentially consisting of potassium fluoride and an aprotic organic solvent having a boiling point higher than that of methanol, which is obtainable by mixing a mixture containing potassium fluoride and 5 to 50 parts by weight of methanol per 1 part by weight of potassium fluoride with the aprotic organic solvent followed by concentrating the obtained mixture, and a process for producing a fluorine-containing organic compound comprising contacting an organic compound having at least one group capable of being substituted nucleophilically with a fluorine atom with the potassium fluoride dispersion.

- 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.
