摘要:
以2-乙基-2-硝基-1,3-丙二醇为原料,经酯化、叠氮化两步反应,合成出了1,3-二(叠氮乙酰氧基)-2-乙基-2-硝基丙烷(ENPEA),总收率为83%。利用红外光谱、核磁共振、元素分析对ENPEA的结构进行了表征。探讨了叠氮化反应的影响因素,确定其最佳反应条件为:n(NaN3)∶n(ENPE)为2.2∶1.0,混合溶剂中水占总体积的13%~20%,反应时间2 h;性能测试得到ENPEA的玻璃化转变温度为-43.4 ℃,热分解峰温为252.4 ℃,密度为1.34 g/cm3,特性落高为120.2 cm(落锤2 kg),爆炸概率为4%(摆角66°)。
Abstract:
1,3-di (azido-acetoxy)-2-ethyl-2-nitropropane (ENPEA) was synthesized using 2-ethyl-2-nitro-1,3-Propanediol as raw material, via two-step reactions of esterification and azidonation at a total yield of 83%. Its structure was identified by IR, NMR and elemental analysis. Influencing factors of azidonation were studied. The optimum conditions of the reactions are: n(NaN3)∶n(ENPE)=2.2∶1.0, 13%-20% of the total volume of acetone-H2O and reaction time of 2 h. Some physicochemical properties of ENPEA were obtained by tests as the glass transition temperature of -43.4℃, the decomposition temperature of 252.4 ℃, the density of 1.34g/cm3, H50 of 120.2 cm (2 kg drop hammer), and the friction sensitivity of 4% (66° oscillation angle).
