Abstract:

采用超声波清洗技术对黑索今(RDX)清洗脱酸, 并对其动力学特征进行了研究。以酸度为评价指标, 通过单因素试验考察了超声作用时间、温度、超声频率、超声功率对RDX清洗脱酸清洗效果的影响, 采用正交试验对超声辅助清洗RDX脱酸试验的工艺条件进行了优化, 建立了超声辅助清洗RDX的脱酸动力学方程, 计算得到相应的活化能。结果表明, 各因素对RDX脱酸效果影响大小依次为:超声作用时间>超声频率>温度>超声功率, 最佳条件为超声时间70 min、温度35 ℃、超声频率40 kHz、超声功率85%, 脱酸过程表现为一级动力学反应, 活化能为7.105 kJ·mol-1, 模型的拟合结果与试验数据吻合较好。超声处理不会改变RDX的分子结构和特征官能团
