为了对退役硝化棉( NC)基固体推进剂中黑索今( RDX)等有效成分进行回收再利用,研究了实验室级别的现代超声辅助提取法( UAE)、开放式聚焦微波辅助提取法( MAE)、加压加热提取法( PLE)及传统的索式提取法( SE)、溶剂溶解水析出法(SDWP),用液相色谱法、红外光谱法对提取效果进行表征。结果表明,PLE的高压可防止硝化甘油(NG)的挥发和分解,用CH2 Cl2作提取剂,能很好溶解RDX等待测物、完全不溶解NC,使得提取物和NC容易分离,提取效率高、时间短,优于其他方法,有望实际应用于大量的退役NC基推进剂中RDX等有效组分的回收利用。
為瞭對退役硝化棉( NC)基固體推進劑中黑索今( RDX)等有效成分進行迴收再利用,研究瞭實驗室級彆的現代超聲輔助提取法( UAE)、開放式聚焦微波輔助提取法( MAE)、加壓加熱提取法( PLE)及傳統的索式提取法( SE)、溶劑溶解水析齣法(SDWP),用液相色譜法、紅外光譜法對提取效果進行錶徵。結果錶明,PLE的高壓可防止硝化甘油(NG)的揮髮和分解,用CH2 Cl2作提取劑,能很好溶解RDX等待測物、完全不溶解NC,使得提取物和NC容易分離,提取效率高、時間短,優于其他方法,有望實際應用于大量的退役NC基推進劑中RDX等有效組分的迴收利用。

In order to recycle and utilize useful component cyclotrimethylenetrinitramine ( RDX) in waste nitrocellulose( NC)?based propellant, the extraction methods of ultra sound?assisted extraction ( UAE ) , open?focus?microwave?assisted extraction (MAE), pressurized liquid extraction (PLE), soxlet's extraction (SE) and organic?solvent?dissolve?water?precipitation (SDWP) were studied in lab. The results, which were characterized by HPLC and IR, show that the method of PLE, in which CH2 Cl2 is used as extractant is efficient and time?saving compared with the other methods. In the method of PLE, the high pressure can pre?vent the volatilzation and decomposition of nitroglycerin (NG).The completely different dissolving performance of RDX and NC in CH2Cl2 is beneficial to seperation of them. PLE is expected to be practically applied to recycle and utilization of useful component RDX from a lot of waste NC based propellant.
