“…Wan et al [9] made a conclusion, by using DSC and ARC, that the initial decomposition reaction of AIBN was accompanied by an endothermic phenomenon. Guo et al [10] found, by using DSC, that the decomposition reaction of AIBN could occur in the solid, solid-liquid and liquid phases.…”

“…One can find a recent paper [33] where such an incorrect procedure leads to improper SADT value of AIBN which was evaluated to be in the range of 60°C, i.e. about 10°C higher compared to other studies [34,35].…”

AbstractThe paper presents the results of the common project performed with the Federal Institute for Materials Research and Testing, Berlin, Germany (BAM) concerning the comparison of the experimental results with simulations based on the application of the kinetic-based method and heat balance of the system for the determination of the Self Accelerating Decomposition Temperature (SADT). The substantial potential of the kinetic-based method is illustrated by the results of the simulation of SADT of Azobisisobutyronitrile (AIBN). The influence of sample mass and overall heat transfer coefficient on the SADT values were simulated and discussed. Simulated SADT values were verified experimentally with a series of large-scale experiments (UN test H.1 [1]) performed with packaging of 5, 20 and 50 kg of AIBN in an oven at constant temperatures. Additionally, the results of small-scale test H.4 for SADT determination based on the heat loss similarity as described in details in the UN Manual [1] were compared with the simulated data based on kinetic approach. The paper presents also the basic principles of a new kinetic analysis workflow in which the heat flow traces (e.g. DSC) are simultaneously considered with results of large scale tests as e.g. H.1 or H.4. Application of the newly proposed kinetic workflow may increase accuracy of simulations of SADT based on results collected in the mg-scale and considerably decrease the amount of expensive and time consuming experiments in kg-scale tests.• Kinetic-based simulations were applied for evaluation of SADT for AIBN • Correct kinetic approach and appropriate heat balance allowed successful scale up • Simulated SADT values were verified experimentally by large-scale experiments • Influence of sample mass and heat transfer coefficient U on SADT was evaluated • New kinetic approach based on merging DSC and large scale data was proposed.

“…Ideally, the DSC experiment should cover the ranges of temperatures and heating rates which will be used during simulation. For azobisisobutyronitrile (AIBN), the SADT is about 50 C [2]. During self-heating due to decomposition, the temperature increases by more than 100 K, whereby the heating rate changes from zero to tens of Kelvin per minute.…”

“…If experimental data do not follow ICTAC recommendations then it leads to significant error like [3], where the erroneously calculated stable temperature for AIBN only from dynamic data in liquid phase is more than 10 K higher than known literature values [2]. Therefore, dynamic data will be used in kinetic analysis here together with isothermal.…”
