Thermal phenomena studies for dicumyl peroxide at various concentrations by DSC

Information about the kinetics and thermal decomposition of dicumyl peroxide (DCPO) is required for safety concerns, due to its wide applications and accident cases. To understand the inherent hazards during DCPO manufacturing, we selected various concentrations in different stages and analyzed them by differential scanning calorimetry (DSC). We evaluated thermokinetic parameters to set up a simple, but comprehensive kinetic model, with various tests conducted at heating rates of 2, 4, 6 and 10 degrees C min(-1). Subsequently, we established a more efficient, resource-effective, and cost-effective model of safety evaluation for DCPO with different concentrations, according to thermokinetic parameters, such as activation energy E-a is 125.35 kJ mol(-1), frequency factor k(o) is 3.124 . 10(12) s(-1), reaction order n is 0.9 and heat of decomposition Delta H is 750.52 J g(-1) for DCPO 99 mass%.
