Abstract
Ultra-fine 2,2',4,4',6,6'-hexanitorstilbene(HNS-IV) was prepared by using solvent/anti-solvent recrystallization method.The effects of solvent factors, drying methods and process parameters, such as different solvents, anti-solvents, washing solvents,temperature,drying methods on the particle size,particle size distribution and morphology of HNS,were investigated. Results show that suitable solvents as follows: dimethylformamide(DMF) was solvent,and H2O was anti-solvent and methanol was wash solvent.The particle size and size distribution can be controled by verifying the amount of solvent, amount of anti-solvent, amount of surfactant,temperature and drying methods. Crystal appearance of HNS is smooth with particle size from 0.5 μm to 1.0 μm.关键词
