“…Chen et al 2006 reported that the hydrogen peroxide concentrations at 31% w/w and heating rate at 10 °C/min, the onset temperature and the peak temperature were 57.8 and 73.1 °C, respectively, while the enthalpy of reaction was 838.9 J/g [8]. The result of this research confirmed that the hydrogen peroxide higher concentration 30% w/w was highly oxidizing hazardous material which easily decomposed due to the weak bond of peroxide (-O-O-) functional group in the structure.…”

Hydrogen peroxide is a strong oxidizing agent containing a peroxide functional group that easily decomposes. In this research, a commercial grade of 35 % w/w hydrogen peroxide was evaluated for thermal hazard and reactivity by differential scanning calorimetry (DSC). It was found that the calculated activation energy was 70.03 kJ/mol. The risk assessment of thermal hazard evaluated in terms of the adiabatic decomposition temperature rise at heating rate 2, 4 and 8 °C/min, were 236.5, 159.2 and 217.5 K, respectively. While the time-to-maximum rate were 79.1, 52.6 and 28.3 second, respectively. Therefore, the storage, transportation and usage, proper care must be highly careful by trained and qualified person or the chemist knowledgeable personnel.

In this study, various calorimetric and analytical techniques were used to evaluate the thermodynamics of the preparation of adipic acid through the oxidation with hydrogen peroxide. The reaction exotherm was combined with the reaction mechanism. Differential scanning calorimetry revealed that the hydrogen peroxide was relatively stable when Na2WO4.2H2O and H2SO4 were used as cocatalysts. Reaction calorimetry, in situ Fourier transform infrared spectroscopy and gas chromatography/mass spectrometry (GC/MS) results indicated a possible macroscopic reaction pathway at 73 and 90°C stage. Furthermore, the results obtained through adiabatic calorimeter (Phi‐TEC II) and GC/MS indicated the possibility of catastrophic accidents if control of the target reaction was lost. The criticality classes of this reaction were of Grade 5. The results of this study can be further used to improve the inherent safety of its operating measures, as a result, this reaction process can be scaled up.
