Study on Thermal Risk Evaluation of Reactive Substance

The chemical kinetic parameters and self accelerating decomposition temperatures (SADTs) of several organic peroxides and asphalt salt mixtures are calculated using heat flux data measured by the C80 calorimeter, and the SADTs are compared to those measured by US measurement test. The estimated SADTs from the C80 data are in good agreement with the SADTs determined by the US measurement test. It proves that the C80 method is an easy, safer and more economic way to evaluate the thermal risk of reactive substance.
