The DSC (Differential Scanning Calorimetry) analysis of heavy ozonized C60
fullerene (known also as“fullerene ozopolymer”),shows the exothermal decomposition of this compound with a peak at 158ºC with a decomposition enthalpy AH_dec aprox 322 kJ/mol
and an activation energy for the decomposition E#=71 kJ/mol. These experimental facts confirm the secondary ozonide/peroxidic and polymeric nature of fullerene ozopolymer originally suggested by the infrared spectroscopy analysis and solid state13C-NMR spectroscopy. It is also shown that the secondary ozonide group of fullerene ozopolymer can be reduced selectively by a treatment with hydrogen iodide.
