摘要
为了给高能炸药提供钝感剂,以提高其安全性能,用甘氨酸、苯甲醛和C60等为原料合成了2-苯基[60]富勒烯吡咯烷衍生物(产物1),探讨并获得了产物1的适宜合成工艺条件:反应物C60、苯甲醛和甘氨酸物质的量之比为1∶4∶6,温度为105℃,反应时间为14 h,此时产率可达到75%(以消耗的C60计)。用FT-IR(傅立叶变换红外光谱)、UV-V is(紫外可见光谱)1、H-NMR(核磁共振氢谱)和MS(质谱)表征了产物1的结构,初步探讨了产物1对HMX(奥克托今)的钝感作用。结果表明,产物1对HMX具有明显的钝感作用,添加质量分数为1%的产物1可使HMX的摩擦感度降低到33%,撞击感度降低到48%。对产物进行了热分析研究,结果表明产物具有很好的热稳定性。
For providing deterrents to high explosive and enhancing its safety property,the glycine,benzaldehyde and C60 are compounded into 2-Phenyl Fullerene pyrrolidine(Product 1) as raw materials.The suitable synthesis technics condition to product 1 is the moore ratio of C60,benzaldehyde and glycine is 1∶4∶6,and the temperature is 105 ℃,the reacting time is 14 h;then the product 1′s ratio was 75%(based on consumed C60).The structure of product 1 is characterized by UV-Vis,FI-IR,MS and 1H-NMR,and probing into the insensitive role on HMX.The results show that the insensitivity of product 1 on HMX is obvious and the 1% product 1 can decrease the friction sensitivity to 33% and the impact sensitivity to 48%.The resutls of thermoanalysis research on products show that it has good thermal stability.
