“…The adiabatic induction time is defined as the time which is needed for self-heating of the sample from the starting temperature to the time of maximum rate (TMR ad ). The precise determination of the time to maximum rate under adiabatic conditions is necessary for the safety analysis of many technological processes [7][8].…”

Dicumyl peroxide(DCPO) is usually employed as an initiator for polymerization, a source of free radicals, a hardener, and a linking agent. The calculation about the kinetics and thermal decomposition of dicumyl peroxide (DCPO) and DCPO mixed with catalysts are required for safety concerns, because of its wide applications and accident cases. The isoconversional kinetic study on the thermal behaviour of DCPO and DCPO mixed with catalysts have been carried out by differential scanning calorimetry. The apparent activation energy E a and pre-exponential factor A are not constant during the reaction. Application of accurate decomposition kinetics enabled the determination of the time to maximun rate under adiabatic conditions (TMRad) with a precision given by the confidence interval of the predicitons. This analysis can then be applied for the examination of the effects of the surrounding termperature for safe manufacturing process.

“…primary runaway hazard due to exothermicity of reaction and secondary runaway hazard due to release of dangerous chemicals from reactor to the surroundings. The primary runaway hazard assessment is based on criticality classes (Stoessel, 1993), probability (time to maximum rate at adiabatic conditions (TMR ad )) and severity (adiabatic temperature rise (DT ad )) (Keller, Stark, Fierz, Heinzle, & Hungerbühler, 1997;Pastre, Wörsdörfer, Keller, & Hungerbühler, 2000) (see Fig. 6).…”
