Experimental Study on the Thermal Hazardous Characteristics of Lauroyl Peroxide

In order to research the thermal hazardous characteristics of lauroyl peroxide (LPO), Accelerating Rate Calorimeter (ARC) was used to test its adiabatic decomposition characteristics, the measured data are modified by consideration of thermal inertia factor of ARC and self-accelerating decomposition temperatures (SADT) of them are calculated. The results show that in totally adiabatic condition, maximum heat release rates of LPO and LPO kept inert by dibutyl phthalate (DBP) are 218.70 °C·min-1 and 11.61 °C·min-1 respectively, SADT of them are 34.72 °C and 43.64 °C respectively. LPO kept inert is safer, keeping it inert is meaningful to production, transport and storage of LPO.
