1,1′-Diisopropylideneamino-5,5′-azotetrozole

Abstract

1,1′-diisopropylideneamino-5,5′-azotetrozole (DPrZT) was synthesized with 1-isopropylideneamino-5-aminotetrozole as the raw material and sodium urate isocyanide dichloride as oxidant. Three of the most important factors which affect the yield of DPrZT were gained from the single factor experiments. Based on the single factor experiments, the orthogonal experiments were carried out. The most optimal experimental condition was gained as follows: In the first stage, the reaction temperature was 30 °C, the reaction time was 20 min, and the dropping temperature was 30 °C; In the second stage, the reaction temperature was 30 °C, the reaction time was 20 min, and n(HAc):n(SDCI) was 0.5. The maximum yield was 89.6 % under the optimum reaction condition. The structure and performance of DPrZT were studied in detail in this paper. It showed good thermal stability and explosive performance. It exhibited prospective application in explosion field.
