Resin is widely used in hydrogen peroxide purification process, but it has a certain role in the decomposition of hydrogen peroxide. The effect of resin on decomposition characteristics of hydrogen peroxide was investigated in this study. Based on the Chinese national standard GB/T1616, hydrogen peroxide stability test was established, and the effect of resin on the stability of hydrogen peroxide was investigated. The thermal stability of hydrogen peroxide and the effect of resin on the samples were obtained by DSC calorimeter. The adiabatic simulation experiment was carried out by VSP2 calorimeter, and the thermal runaway reaction characteristics of hydrogen peroxide-resin system under adiabatic conditions were obtained. By fitting regression of the adiabatic calorimetric experimental data, the kinetic parameters of the experimental system were obtained, and the TMRad was calculated to be 5.9 h. The experimental results show that the stability of hydrogen peroxide decreases obviously with the addition of resin, and the uncontrolled decomposition of hydrogen peroxide easily occurs under adiabatic conditions, which has great potential safety hazards.
