摘要
为建立安全、高效、绿色钝感奥克托今(HMX)制备方法,分别以甲基咪唑硝酸盐([mimH]NO3)、丁磺酸甲基咪唑硝酸盐([mimBSO3H]NO3)、三乙胺硝酸盐([Et3NH]NO3)、丁磺酸三乙胺硝酸盐([Et3NBSO3H]NO3)为晶型助剂,丙酮、环己酮为溶剂,采用溶剂-非溶剂法重结晶制备降感HMX。结果表明,在离子液体[mimBSO3H]NO3(质量为HMX的1.5%)存在的条件下,以环己酮为溶剂,在60℃,搅拌速度750 r·min-1条件下对HMX重结晶可使HMX晶体趋于球形化。所得HMX晶体表面光滑,边缘整齐,热分解峰温提高到288℃,撞击感度4%。
in order to establish a safe,effective and green method,the reduced-sensitivity HMX was prepared by recrysta[lization from ionic liquid-solvent system with solvent-nonsolvent technique, using a series of ionic liquids [mimHl NO3, [mimBSO3H] NO3, [Et3NH]NO3 and [ Et3NBSO3H] NO3 as crystal assistants, acetone and cyclohexanone as solvent. Results show that the reduced- sensitivity HMX with spherical crystal can be recrystallized at 60 ℃ at the stirring rate of 750 r· min^-1 in the presence of ionic liquid [ mimBSO3 H] NO3 （1.5% weight of HMX） using cyclohexanone as solvent. The obtained HMX is smooth surface and neat edge with thermal decomposition peak temperature of 288 ℃ ,and impact sensitivity of 4%.
