摘要
以5-氨基四唑一水化合物(5-AT·H2O)为原料,与硝酸反应一步制得5-氨基四唑硝酸盐(5-ATN)。研究了硝酸用量、反应温度和反应时间对目标物合成的影响。通过正交实验得到最优合成工艺:20℃下,5 g 5-AT·H2O与15 mL浓硝酸(65%)边搅拌边反应15 min,目标物产率达92.6%。和文献报道比较,该工艺反应温度降低、时间缩短、产率提高。表面形貌分析与吸湿性测试结果表明目标产物晶体表面光滑、吸湿性低。
5-Aminotetrazolium nitrate（5-ATN）was synthesized from 5-aminotetrazole monohydrate（5-AT·H2O）and concentrat-ed nitric acid. The effects of nitric acid dosage,reaction time and reaction temperature on the yield of 5-ATN were discussed. The proper synthesis conditions determined by orthogonal experiments were as follows：5 g 5-AT,15 mL nitric acid,reaction tempera-ture 20 ℃ and reaction time 15 min,with the yield of 92. 6%. Compared with previous studies,the reaction temperature and reaction time decrease while the yield is improved. SEM picture shows that the surface of 5-ATN is smooth,and hellogh humidity storage tests show that the water absorption of product is reduced.
