摘要

Organic peroxides (OPs) and inorganic peroxides (IPs) are usually employed as an initiator for polymerization, a source of free radicals, a hardener, and a linking agent in low density polyethylene (LDPE), polyvinyl chloride (PVC), controlled-rheology polypropylene (CR-PP), and styrene industries. Worldwide, due to their unstably reactive natures, OPs and IPs have caused many thermal explosions and runaway reaction incidents. This study was conducted to elucidate its essentially hazardous characteristics. To analyze the runaway behavior of OPs and IPs in the traditional process, thermokinetic parameters, such as heat of decomposition (ΔHd), exothermic onset temperature (T0), self-accelerating decomposition temperature (SADT), half-life time, time to maximum rate (TMR), critical temperature (Tc), etc., were measured by calorimetric approaches and calculation method. Generally speaking, safety and health handling information of hazardous materials and toxic substances is noted in material safety data sheets (MSDS), but MSDS are not providing important handling indicators. In view of loss prevention, more useful indicators must be provided in the sheets or guide book.
