1-Amino-3-methyl-1 ,2,3-triazolium nitrate(1-AMTN ) was synthesized using glyoxal and hydrazine hydrate as starting materials in three steps, I.e. Addition-elimination, cyclization, methylation and replacement reaction. The overall yield is 71.8% (based on glyoxal). The structure of products was confirmed by IR,MS,NMR and elemental analysis. The properties of 1-AMTN were estimated: density 1.63 g ? Cm -3 ,enthalpy of formation 84 kJ ? Mol-1 and detonation velocity 8115 m ? S-1. The key factors of cyclization and methylation were studied and the optimal reaction conditions were confirmed: medium acetonitrile,20 ℃,and the ratio of glyoxal bishydrazone and methyl Iodide 1 : 5. The overall yield of cyclization and methylation is 86. 7%. In addition,actived manganese oxide was recycled and its mechanism was also discussed.%以乙二醛和水合肼为起始原料,经加成-消除、环化甲基化、置换反应得到1-氨基-3-甲基-1,2,3-三唑硝酸盐(1-AMTN),总收率71.8％(以乙二醛计),采用核磁(NMR)、红外(IR)、质谱(MS)和元素分析对产物进行了表征.预测了1-AMTN的性能:密度为1.63 g· cm-3,生成焓84 kj·mol-1,爆速8115 m·s-1.研究了溶剂、温度、物料比对产物得率的影响,确定了环化甲基化的最佳反应条件:溶剂为乙腈,反应温度20℃,乙二腙与碘甲烷的物料比1:5,环化甲基化收率为86.7％.对活性二氧化锰进行了回收利用并对其机理进行了探讨.
