Thermal Hazard Analysis of Typical Binary Nitro Compounds
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.
