    Abstract: The present invention provides a composition for use in refrigeration and air-conditioning comprising: a) at least one refrigerant selected from the group consisting of hydrofluorocarbon, hydrochlorofluorocarbon, fluorocarbon, and chlorofluorocarbon; and b) a sufficient amount to provide lubrication of at least one polyoxyalkylene glycol. The polyoxyalkylene glycol has at least one pendant non-terminal perfluorinated alkyl group on its hydrocarbon polymer backbone. The polyoxyalkylene glycol is terminated with a group selected from the group consisting of hydrogen, alkyl, and fluoroalkyl. The polyoxyalkylene glycol has a molecular weight of about 300 to about 4,000 and a viscosity of about 5 to about 300 centistokes at 37 °C. The polyoxyalkylene glycol is miscible in combination with the refrigerant in the range between about -40 °C and at least about +20 °C.

    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.
