Ammonium perchlorate (AP) is used as a strong solid oxidizer in propellants, gun powder, fireworks, and light signals. Recycling or recovery of AP from demilitarization or outdated propellant items is a challenging task. Herein, we report the purchase of recycled crude AP from commercially, and then subsequently AP was purified through filtration with activated carbon and recrystallization. After recrystallization, the yield of AP was 85 %, and the resultant product was characterized by various techniques including Fourier‐transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, X‐ray diffraction, scanning electron microscopy, and inductively coupled plasma mass spectrometry. These results indicate that recrystallized AP had excellent purity and crystallinity compared to crude AP. In addition, purified AP was used as source material for the synthesis of lithium perchlorate (LP), which was characterized using various analytical techniques. This process provides a new avenue for recycled AP that could be effectively used as starting material for synthesis of LP.

从过时弹药中回收高氯酸铵及其在高氯酸锂合成中的应用

高氯酸铵（AP）在推进剂，火药，烟火和光信号中用作强氧化剂。从非军事化或过时的推进剂中回收或回收AP是一项艰巨的任务。本文中，我们报告了从商业购买再生的粗制AP，然后通过活性炭过滤和重结晶将AP纯化。重结晶后，AP的产率为85％，并通过多种技术对所得产物进行表征，包括傅立叶变换红外光谱，核磁共振光谱，X射线衍射，扫描电子显微镜和电感耦合等离子体质谱。这些结果表明，与粗制AP相比，重结晶的AP具有优异的纯度和结晶度。此外，纯化的AP用作合成高氯酸锂（LP）的原料，并使用各种分析技术对其进行了表征。此过程为回收的AP提供了新途径，可以有效地用作LP合成的起始原料。
