摘要
文章选择了 2,4-二硝基苯胺、2,6-二硝基苯胺和 1,4-二硝基苯 3 种典型的二元硝基化合物作为实验对象,通过差示扫描量热实验(DSC)、热重实验(TG/DTG)和绝热加速量热实验(ARC)分析了 3 种物质的分解过程,获取了热危险性数据和动力学参数.结果表明,3 种物质的分解过程均可分为三个阶段,即能量缓慢释放阶段、能量积聚阶段和能量爆发阶段,在物质储运过程中需要严格控制温度,防止物质进入能量爆发阶段;3 种物质的危险性程度由高到低依次为2,4-二硝基苯胺、2,6-二硝基苯胺、1,4-二硝基苯.
Abstract
In this study,three typical binary nitro compounds,2,4-dinitroaniline,2,6-dinitroaniline and 1,4-dinitrobenzene,were selected as the experimental objects.The decomposition processes of three substances were analyzed by differential scanning calorimetry(DSC),thermogravimetry(TG/DTG)and adiabatic accelerated calorimetry(ARC),then their thermal hazard datas and kinetic parameters were obtained.The analysis results show that the decomposition process of the three substances can be divided into three stages,namely the slow energy release stage,the energy accumulation stage,and the energy explosion stage.During the storage and transportation of the material,it is necessary to strictly control the temperature to prevent the material from entering the energy explosion stage.The degree of danger of the three substances in descending order is 2,4-dinitroaniline,2,6-dinitroaniline,and 1,4-dinitrobenzene.
