摘要/Abstract

摘要： 为规避偶氮二异丁酸二甲酯(AIBME)的潜在热危险,使用差示扫描量热仪(DSC)研究其热分解过程,并利用Kissinger法初步计算活化能;通过热安全软件(TSS)进行数据拟合,得到AIBME的活化能及相关动力学参数,与Kissinger法所得活化能进行比较;利用所得动力学参数建立热动力学模型,推算AIBME的自加速分解温度(SADT)和最大反应速率到达时间(TMRad)。研究结果表明:TSS进行分步式热分解分析所得AIBME的活化能比Kissinger法所得活化能更准确,所得第一阶段分解所需活化能为88.44 kJ/mol,第二阶段为113.87 kJ/mol;AIBME的SADT为30 ℃,在常温下可分解,故在生产、运输和储存过程中应加强温度的监控。

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)
