Thermal Stability of Epoxidized and Carbonated Vegetable Oils

Biomass valorization processes are being used more frequently in industry. These processes are greener because they use some renewable and biodegradable raw materials, but are they safer? We propose to study the thermal stability of different epoxidized and carbonated vegetable oils. The severity of the thermal risk, i.e., adiabatic temperature rise, was determined by using differential scanning calorimetry tools. The probability of the thermal risk, i.e., time-to-maximum rate under adiabatic conditions, was determined by using an accelerating rate calorimeter. By analyzing these safety criteria, we have found that the thermal risk, essentially during storage and reactor loading, can be assumed to be negligible.
