Abstract:3, 4-Diaminofurazan was prepared from 3, 4-diaminoglyoxime by two new methods. Supported solid alkali or micelle was used as catalysts in the reaction first time. When the reaction catalyzed by supported solid alkali, the optimal conditions are: 150 ℃, 3, 4-diaminoglyoxime:supported solid alkali:H2O(mass)=1:3.5:12.5, 4 h. Under those conditions, the yield could be improved to 91.2%. The temperature, pressure and catalyst amount are lower and yield is higher than the reaction catalyzed by KOH. Moreover, the catalyst can be reused at least five times without decreasing of catalyst activity. Then, 3, 4-diaminofurazan synthesis catalyzed by micelle was explored. Anionic and cationic surfactants both possessed well catalytic activity when the mass ratio of surfactant and 3, 4-diaminoglyoxime was 0.02. On the condition of 110 ℃, DAG:KOH:H2O:sodium dodecyl benzene sulfonate(mass)=1:1.3:7.1:0.02, when the reaction time was 10 h, the yield was 46.0%. Compared with the reaction without catalyzed by micelle, the cite reaction could react at lower temperature and pressure.
