Methyl ethyl ketone peroxide (MEKPO) possesses complex structures which have caused many incidents involving fires or explosions by mixing with incompatible substances, external fires, and others. In this study, reactivities or incompatibilities of MEKPO with inorganic acids (HCl, HNO3, H3PO4 and H2SO4) were assessed by differential scanning calorimetry (DSC) and vent sizing package 2 (VSP2). Parameters obtained by the above-mentioned devices could be readily employed to discuss the runaway reaction, such as onset temperature (T-0), heat of reaction (Delta H-d), time to maximum rate (TMR), maximum self heat rate (dT/dt)(max) adiabatic temperature rise (Delta T-ad), maximum pressure of decomposition (P-max) and so on. Mixing MEKPO with hydrochloric acid resulted in the lowest T-0 among inorganic acids. Nitric acid not only lowered the T-0 but also delivered the highest heat releasing rate or self heat rate (dT/dt), which was concluded to be the worst case in terms of contamination hazards during storage or transportation of MEKPO.
