Prepartion and Crystal Control of Desensitized-RDX

WANG Yuan-yuan,LIU Yu-cun,WANG Jian-hua,LIU Deng-cheng(College of Chemical Engineering and Environment,North University of China,Taiyuan 030051,China)  
The desensitized RDX was prepared by the method of solvent-nonsolvent recrystallization,the effect of different conditions,such as temperature,solvents,surface-active agents,stirring strength and feeding modes was studied.The results obtained by an optical microscope,SEM and the impact sensitivity test show that the crystal shape and inner quality of crystallized RDX are improved and the impact sensitivity is reduced adopting the best process conditions:70℃,DMSO-solvent,methanol-nonsolvent,dextrin-surface active agent,1 000 r/min stirring strength.The different sizes by controlling RDX concentration of initial solution was gained.The impact test results indicate that the impact sensitivity of granuration 100-120 μm is decreased by 34%.
