    摘要:

    提出了从不同恒速升温速率(β)条件下的DSC曲线起始温度(T0)、onset温度(Te)、峰温(Tp)、TeTp处的反应转化率αeαp及相应各等转化率αiβiTα,i (i=1, 2, …, L)数据计算/确定含能材料放热分解反应Arrhenius/非Arrhenius动力学参数的方法。用该法得到了四水双(3-(5-硝基-1, 2, 4-三唑))钠[Na2(BNT)(H2O)4]放热分解反应的Arrhenius/非Arrhenius动力学参数。用所得非Arrhenius动力学参数计算了[Na2(BNT)(H2O)4]的热爆炸临界温度(Tb),并与用Arrhenius动力学参数所得的Tb值作了比较。验证了本工作所得[Na2(BNT)(H2O)4]非Arrhenius动力学参数的有效性和可靠性。

    Abstract:

    A method of computing/determining the Arrhenius/non-Arrhenius kinetic parameters of the exothermic decomposition reaction of energetic materials (EMs) was presented from initial temperature (Te), peak temperature (Tp), conversion degree (αei or pi) at Tei or pi and data (βiTα,i, i=1, 2, …, L) corresponding to isoconversation degree (αi) for DSC curves under different constant heating rate (β) conditions. The Arrhenius/non-Arrhenius kinetic parameters of the exothermic decomposition reaction of sodium cis-bis(3-(5-nitro-1, 2, 4-triazolate tetrahydrate) [Na2(BNT)(H2O)4] were obtained by this method. The critical temperature of thermal explosion (Tb) of [Na2(BNT)(H2O)4] was calculated by the non-Arrhenius kinetic parameters obtained and compared with the value of Tb obtained by Arrhenius kinetic parameters. The validity and reliability of non-Arrhenius kinetic parameters of [Na2(BNT)(H2O)4] obtained in this work were verified.
