摘要:
采用常规洗涤技术和超声波洗涤技术对比研究了黑索今(RDX)的洗涤驱酸过程及其动力学特征。考察了不同洗涤条件如液固比、时间、温度等对RDX常规洗涤与超声波洗涤过程的影响规律；通过对2种洗涤方式下RDX洗涤驱酸过程的动力学分析，建立了符合的动力学方程，并计算得到相应的表观活化能。结果表明，超声波洗涤驱酸效果优于常规洗涤驱酸效果；2种方式下的洗涤驱酸过程表现为一级动力学反应，且常规洗涤表观活化能12.221 kJ/mol,大于超声波洗涤的表观活化能7.105 kJ/mol，说明超声洗涤更容易；并且超声洗涤驱酸过程不会改变RDX的分子结构和特征官能团。
Abstract:
Deacidification process and dynamic characteristics of RDX were comparatively investigated by conve tional washing technique and ultrasonic washing technique. Effects of washing conditions, such as liquidsolid ratio, time and temperature, on the process of ultrasonic washing and conventional washing were discussed. Related dynamic model was deduced and apparent activation energy was obtained by the dynamic analysis of the two washing methods. Results reveal that effect of ultrasonic washing is better than that of conventional cleaning, and the two deacidification processesare in conformity with pseudofirst order kinetics.Apparent activation energy of conventional washing is 12.221 kJ/mol, which is higher than that of ultrasonic washing (7.105 kJ/mol), and it means that ultrasonic washing is easier to be cleaned.Ultrasonic deacidification process brings no changes of the molecular structure and representative functional groups of RDX.
