Comparison of the Isothermal and Non-Isothermal Kinetics for Predicting the Thermal Hazard of Tert-Butyl Peroxybenzoate

Abstract:

Tert-butyl peroxybenzoate (TBPB), a liquid organic peroxide, has been widely employed in the petrifaction industry as a polymerization formation agent. This study investigated the thermokinetic parameters of TBPB by isothermal kinetic algorithms and non-isothermal kinetic equations, using thermal activity monitor III (TAM III) and differential scanning calorimetry (DSC), respectively. Simulations of 0.5 L, 25 kg, 55 gallon, and 400 kg reactors in liquid thermal explosion models were performed. It is based on the thermal hazard properties, such as the heat of decomposition (∆H_d), activation energy (E_a), self-accelerating decomposition temperature (SADT), control temperature (CT), emergency temperature (ET), and critical temperature (TCR). From the experimental results, the optimal conditions to avoid violent runaway reactions during the storage and transportation of TBPB were determined.
