摘　　要：采用超声波技术，以水为清洗介质，对酸度0．8％～1．4％的 RDX 进行了洗涤脱酸动力学实验，用最小二乘法对实验数据进行了拟合回归。结果表明，在15～35℃、60～80 min 可实现含酸 RDX 的洗除脱酸效果达到98％以上；脱酸过程表现为一级动力学反应，表观活化能为10．87 kJ/mol，指前因子为3．9976 min^-1。Ultrasonic technique was applied into deacidification kinetic experiments of RDX in water.Acidity of RDX was between 0.8% to 1 .4%.The experimental data was fitted by the least square method.The results show that more than 98% deacidification effect can be completed under relative lower temperature （15 -35℃）within relative shorter period （60-80 min）.The deacidification processes can be described by first order kinetic model,the activa-tion energy is 10.87 kJ/mol,and the pre-exponential factor is 3.997 6 min^-1 .
