一种1-氧-2,6-二氨基-3,5-二硝基吡嗪的制备方法
摘要：
本发明提供一种1-氧-2,6-二氨基-3,5-二硝基吡嗪的制备方法，该方法以2,6-二氨基-3,5-二硝基吡嗪为原料，依次将冰醋酸、2,6-二氨基-3,5-二硝基吡嗪、双氧水和顺丁烯二酸酐加入到反应瓶中，2,6-二氨基-3,5-二硝基吡嗪与冰醋酸的质量比为1:15～40，与双氧水的质量比为1:3～7，与顺丁烯二酸酐的质量比为1:0.4～0.8，然后升温至70℃～100℃，反应2h～10h后，得1-氧-2,6-二氨基-3,5-二硝基吡嗪。本发明提供的合成方法，克服了背景技术制造成本高、环境污染大、反应时间长的缺陷。
摘要（英）：

The invention provides a preparation method of 1-oxy-2, 6-diamido-3, 5-dinitropyrazine. The method comprises the following steps: sequentially adding glacial acetic acid, 2, 6-diamido-3, 5-dinitropyrazine serving as the raw material, hydrogen peroxide and maleic anhydride to a reaction flask, wherein the mass ratio of 2, 6-diamido-3, 5-dinitropyrazine to glacial acetic acid is 1: (15-40), the mass ratio of 2, 6-diamido-3, 5-dinitropyrazine to hydrogen peroxide is 1: (3-7), and the mass ratio of 2, 6-diamido-3, 5-dinitropyrazine to maleic anhydride is 1: (0.4-0.8); heating to reach the temperature of 70 to 100 DEG C; reacting for 2 to 10 hours to obtain 1-oxy-2, 6-diamido-3, 5-dinitropyrazine. The synthesis method overcomes the shortages of high cost, large environmental pollution and long reaction time in the background technology.
