    Abstract: A process for producing a fluorinated organic compound comprising: (a) reacting an organic starting material with hydrogen fluoride in the presence of a fluorination catalyst and an HFC reaction solvent to produce a product stream containing the fluorinated organic compound wherein the reaction solvent has a boiling point higher than that of the fluorinated organic compound; and (b) recovering the fluorinated organic compound from the product stream.

    Abstract: The preparation of carbon fluoride and carbon fluoride chloride from a graphite intercalate is described. Treatment of group V-A pentahalide intercalates of graphite with fluorine or fluorine/chlorine gas mixtures at a temperature of about 300°C results in the production of highly fluorinated CFx: x 1 or (CyFxClz)n: x 1.0, z 0.1, y = 1. In the process, carbon fluoride or carbon fluoride chloride can be prepared from a highly ordered graphitic carbon at a temperature substantially lower than that of the decomposition temperature of the product, CFx or (CyFxClz)n. In particular, carbon fluoride or carbon fluoride chloride is prepared from a group V-A pentahalogen intercalate and fluorine gas or fluorine/chlorine gas mixtures at temperatures in the order of 250-300°C. The process provides a controlled, reproducible method of preparing a carbon fluoride or carbon fluoride chloride material from a graphite feedstock having fluorine-to-carbon ratios of 1 or greater from the pentahalide compound and fluorine gas or fluorine/chlorine gas mixtures at temperatures substantially removed from the decomposition temperature of the final product, thus eliminating the potential of an explosive reaction or the formation of unstable by-products.
