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 CF1.09, cp 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 CF1.12s 1.12 Li s yielding 1.12 LiFs Cs. 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.
