Study on thermal hazards for isoprene monomer (IPM) mixed with aluminum oxide

Abstract

Isoprene monomer (IPM) is a colorless, volatile liquid obtained from petroleum or coal tar that occurs naturally in many process plants. It is used chiefly to make synthetic rubber. Our study used calorimetric approaches to conduct thermal analysis and hazard assessment of aluminum oxide (Al2O3) and IPM relevant studies. Differential scanning calorimetry, thermal activity monitor III, thermogravimetry, and vent sizing package 2 were used to discuss thermal instability reaction of Al2O3, which adsorbed IPM, and find every possible reason for cases of fire to prevent any future recurrence of the package store and transport related hazards. By means of calorimetric analysis technology, we can observe thermal decomposition or mass loss for different adsorbed concentrations of IPM and Al2O3 to discuss the related thermal stability parameters, such as exothermic onset temperature (T 0), heat of decomposition (ΔH d), self-accelerating exothermic rate (dT dt −1), pressure rise rate, and maximum reaction temperature (T max). Then, we can understand the potential hazard factors that contribute to disasters related to processing, transport, and storage of security controls and reaction process design.
