Abstract: The most serious thermal decomposition process of CYHPO (cyclohexanone peroxide) is investigated by accelerating rate calorimeter (ARC). The curves of thermal decomposition characteristic parameters versus time for the systems are obtained. The reaction kinetic parameters are calculated by the rate constant method. Modified by the thermal inertia factor, the temperature related parameters at the worst condition is obtained which can reflect the intrinsic thermal hazard of CYHPO. Based on reaction kinetic parameters and Semenov thermal explosion theory, the thermal hazard parameters such as TMRad, θNR, SADT, which are crucial in industry, are calculated. It is proved that the influence of instrumental error of ARC on the results can be neglected. The loading quality of CYHPO should not be exceeding 25kg and the optimal package is type K for this kind of package, the control temperature and emergency temperature should be lower than 59. 7℃.

Key words: cyclohexanone peroxide (CYHPO), accelerating rate calorimeter (ARC), thermal hazard, self-accelerating decomposition temperature, reaction kinetic parameters
