Enthalpies of combustion and formation of fullerenes by micro-combustion calorimetry in a Calvet calorimeter

A set of micro-combustion bombs has been adapted to a Setaram C80 Calvet calorimeter. The calorimetric constant of the micro-bomb in the measurement fluxmeter was determined by combustions with benzoic acid NIST 39j, giving an uncertainty of less than 0.03% for calibration. The experimental methodology of applying this micro-combustion device to the measurement of the energy of combustion of graphite, C60 and C70 is described. Accuracy of better than 0.08% is obtained in some cases.
