    • Diazido derivatives of pentaerythritol are prepared by reacting 3,3-bis(azidomethyl) oxetane with inorganic acids such as hydrobromic or nitric acid. The resulting diazido monobromide can be reacted with sodium azide to produce pentaerythritol triazide which can be subsequently nitrated to pentaerythritol triazido mononitrate. The pentaerythritol diazido mononitrate produced by the reaction of nitric acid with the above oxetane can be further nitrated with nitric acid to produce pentaerythritol diazido dinitrate. These diazido and triazido derivatives of pentaerythritol can be utilized as energetic azido plasticizers per se or can serve as intermediates for the production of such plasticizers.
    • 通过使3,3-双(叠氮基甲基)氧杂环丁烷与无机酸如氢溴酸或硝酸反应制备季戊四醇的二叠氮衍生物。 所得到的重氮化物一溴化物可与叠氮化钠反应,制备季戊四醇三氮化硼,随后可将其硝化为季戊四醇三氮杂一硝酸酯。 通过硝酸与上述氧杂环丁烷的反应制备的季戊四醇二硝基二硝酸盐可以进一步用硝酸硝化以制备季戊四醇二硝酸二叠氮化物。 季戊四醇的这些二叠氮基和三叠氮基衍生物本身可用作能量叠氮增塑剂,或者可以作为生产这种增塑剂的中间体。
