Thermal decomposition of tricyclohexylidene triperoxide

The thermal decomposition of tricyclohexylidene triperoxide both pure and in 4% w/w solution of n-dodecane to yield mainly 16-hexadecanolide is studied applying the nonparametric kinetics method to a set of scanning calorimetry records. The apparent energies of activation obtained are 148.4 ± 0.8 and 90.9 ± 0.8 kJ mol⁻¹, respectively. Combined kinetic models are proposed (first order + Šesták–Berggren) to describe the processes. The isothermal decomposition of the pure peroxide is studied, indicating that there is no appreciable reaction after 12 h at temperatures below 103 °C and that conversion is complete at temperatures over 137 °C.
