Pooling lauroyl peroxide (LPO) with nitric acid, we used differential scanning calorimetry (DSC) to assess the thermokinetic
parameters, such as exothermic onset temperature (T0), heat of decomposition (ΔHd), frequency factor (A), and the other safety parameters. When LPO was contaminated with nitric acid (HNO3), we found the exploder 1-nitrododecane. Obvious products were sensitive and hazardous chemicals. Concentration reaching
1–12 N HNO3 emitted a large amount of heat. This study combined with curve-fitting method to elucidate its unsafe characteristics and
thermally sensitive structure to help prevent runaway reactions, fires and explosions in the process environment. According
to the findings and the concept of inherently safer design, LPO runaway reactions could be adequately prevented in the relevant

Lauroyl peroxide (LPO) is a typical organic peroxide that has caused many thermal runaway reactions and explosions. Differential
scanning calorimetry (DSC) was employed to determine the fundamental thermokinetic parameters that involved exothermic onset
temperature (T0), heat of decomposition (ΔHd), and other safety parameters for loss prevention of runaway reactions and thermal explosions. Frequency factor (A) and activation
energy (Ea) were calculated by Kissinger model, Ozawa equation, and thermal safety software (TSS) series via DSC experimental data.
Liquid thermal explosion (LTE) by TSS was employed to simulate the thermal explosion development for various types of storage
tank. In view of loss prevention, calorimetric application and model analysis to integrate thermal hazard development were
necessary and useful for inherently safer design.
It is our honor and pleasure to discuss some phenomena of specific organic peroxide with Prof. M. Malow and Prof. K. D. Wehrstedt.
