Thermal Hazard Evaluation of Hydrogen Peroxide Solution

Abstract

The thermal decomposition characteristic parameters of 30% hydrogen peroxide (H2O2) were tested by Rapid Screening Device for Safety Calorimeter (RSD) and Accelerating Rate Calorimeter (ARC). The risk of thermal runaway reaction of 30% hydrogen peroxide (H2O2) was assessed with the evaluation method specified by the « Guidelines for Safety Risk Assessment of Fine Chemical Reactions (Trial Implementation) ». The results show that the decomposition heat of 30% H2O2 is 396.280 J/g, the onset temperature is 53.096°C, the adiabatic temperature rise (ΔTad) is 14.294 °C, and the thermal hazard risk level is grade II. Therefore, the control of storage temperature of hydrogen peroxide should be strengthened. In addition, the study also shows that ATMP can inhibit the thermal hazard risk of hydrogen peroxide to a certain extent.
