Comparative analysis of thermal characteristics of higher fullerenes when heated in a nitrogen atmosphere

To study the behavior of higher fullerenes Cn (n = 84, 90, 94) under thermal exposure in a nitrogen medium, a thermodynamic modeling method is used, the main task of which is to determine the phase, chemical composition and parameters of the system under study. This method consists of analyzing the system using the TERRA program, which is a further development of the ASTRA program package. For Cn-N2 systems, a comparative study of ongoing chemical reactions was carried out. Intervals of thermal stability of the condensed phase for higher fullerenes are revealed. The periods of thermal destruction in the gas phase in the systems under consideration are determined.
