摘　　要：利用差示扫描量热仪(DSC)以及热动力学分析软件(AKTS)对30%双氧水进行热稳定性研究.通过不同升温速率的测试,获得了双氧水在不同扫描升温速率下的热分解规律.利用AKTS软件模拟计算,得到了双氧水的热动力学参数.采用风险矩阵评估法评估了双氧水热分解的危险性.结果表明:随着升温速率的提高,30%双氧水的起始分解温度和最大放热温度都升高,放热量为670~714J/g;分解反应活化能为42.5~60kJ/mol;模拟计算了30%双氧水在绝热条件下反应体系达到最大反应速率所需要的时间为1h的温度TD1=37.1℃;利用风险矩阵评估法评估了30%双氧水的安全风险等级为Ⅱ级,属于有条件接受风险.The thermal stability of 30% H2 O2 is studied by differential scanning calorimetry(DSC)and thermodynamic analysis software(AKTS).The thermal decomposition characteristics of H2 O2 at different heating rates are obtained by differential scanning calorimetry.The thermodynamic and kinetic parameters are calculated with AKTS.The risk of thermal decomposition of H2 O2 is evaluated by risk matrix method.The results shows that the rise of heating rate can raise both initial and peak exothermic temperatures of 30% H2 O2,and the heat release is 670~714 J/g.The activation energy of H2 O2 is calculated to be 42.5~60 kJ/mol.The TD1(the temperature at which the 30% H2 O2 reaches maximum reaction rate in 1 h under adiabatic conditions)is 37.1℃.The security risks grade of H2 O2 is Grade Ⅱ,which belongs to conditional acceptance of risk.
