Synthesis of aminoguanidinium 1-methyl-5-nitriminotetrazolate

摘要:

摘 要：以5-氨基四唑为原料，经过甲基化和硝化制得1-甲基-5-硝胺基四唑，而后与氨基胍碳酸氢盐反应得到1-甲基-5-硝胺基四唑氨基胍盐。研究了反应温度、时间、物料比、碱用量和溶剂用量对甲基化反应的影响，优化后产率达44%，比文献值提高3%；还研究了硝化剂用量、反应温度、时间对1-甲基-5-硝胺基四唑产率的影响，优化后产率为81%。 并通过1HNMR、IR、MS等对产物进行了表征。

Abstract:

Abstract: aminoguanidinium 1-methyl-5-nitriminotetrazolate have been prepared by reacting aminoguanidine bicarbonate with 1-methyl-5-nitriminotetrazole which is obtained from 5-aminotetrazole through methylation and nitration.Reaction temperature, time, material ratio, alkali concentration and the amount of solvent were studied about effects on the methylation reaction, and the optimized yield was 44% which was 3% higher than literature values.Then,Nitration dosage, reaction temperature and time were also investigated into nitrification yield,and the optimized yield was 81%. the products were characterized by 1HNMR,IR,MS,etc.
