Thermodynamic, Electrochemical and Synthetic Studies of the Graphite- Fluorine Compounds CF and C4F

Abstract

Samples of the solid fluorocarbons CF and C4F have been prepared by direct fluorination of pure graphite. Low temperature heat capacity measurements have been made on both of these samples using a hydrogen cryostat calorimeter. For the compound CF(1.09, c(p) has been measured over the temperature range 5-310 K. Values of S and G have been calculated over this range of temperature also. It was possible to calculate the theoretical E for an electrochemical cell using the overall reaction CF(1.12)(s) +1.12 Li (s) yielding 1.12 LiF(s) +C(s). The value of the heat of formation at 298K for CF (0.2369) has been derived from the energy of combustion in fluorine for the sample of C4F. In addition, low temperature (15-57 K) cp data was gathered for this compound.
