Abstract

Abstract: To avoid the potential thermal risk of AIBME, the thermal decomposition process of AIBME was studied by DSC. The thermal kinetic parameters of AIBME were acquired by fitting the data with Kissinger equation and TSS. The SADT and the TMRad were calculated based on these parameters. The results show that TSS gives a better performance than Kissinger equation does, that the decomposition reaction involves two stages, and the activation energy of the first stage is 88.44 kJ/mol, the second stage is 113.87 kJ/mol, that the SADT value of AIBME is 30 ℃, and it can decompose at room temperature, and that temperature monitoring should be strengthened during production, transportation and storage of AIBME.

Key words: dimethyl 2,2'-azobis(2-methylpropionate) (AIBME), differential scanning calorimetry (DSC), thermal safety software (TSS), self-accelerating decomposition temperature (SADT), time to maximum rate under adiabatic conditions(TMRad)
