ABSTRACT

The enthalpies of sublimation of fullerenes, as measured in the interval of 810-1170K by thermogravimetry and applying the Langmuir equation, are reported.The detailed experimental procedure and its application to fullerenes C60, C70, C76, C78 and C84 are supplied.The accuracy and uncertainty associated with the experimental results of the enthalpy of sublimation of these fullerenes show that the reliability of the measurements is comparable to that of other indirect high-temperature methods.The results also indicate that the enthalpy of sublimation increases proportionally to the number of carbon atoms in the cluster but there is also a strong correlation between the enthalpy of sublimation and the polarizability of each fullerene.
