Thermal hazard analysis of cumene hydroperoxide using calorimetry and spectroscopy

Organic peroxides have been widely used in industries and are known to be self-reactive chemicals. In this paper, thermal and infrared spectroscopic analyses were carried out to obtain a better understanding of the thermally hazardous behavior of cumene hydroperoxide (CHP) with cumene solvent. The temperature and heat flow profiles of different concentrations of CHP at scanning and isothermal conditions were measured with a small scale reaction calorimeter. Furthermore, probe type in situ infrared spectroscopic measurements were performed and the reaction mechanism will be discussed in regards to both energy release and product identification.
