Synthesis and Characterization of Pentanol-3-nitraza-5-azidonitrate

用N-硝基二乙醇胺二硝酸酯(DINA)和叠氮化钠为原料,在二甲基亚砜中反应合成了一种分子中含—N—NO2,—N3,—ONO2基团的新型含能增塑剂,3-硝基-5-叠氮基-3-氮杂戊醇硝酸酯(PNAN)(粗品)。粗产品经硅胶柱色谱分离净化。所得纯产品的纯度为98.60%。纯产品的结构用IR、1 H NMR及元素分析表征。测试得到PNAN的密度为1.46-3g·cm,热分解温度为172℃,玻璃化转变温度为-41℃,粘度为19.5 mPa·s,摩擦感度为12%,撞击感度为56%。

A novel energetic plasticizer containing —N—NO2,—N3 and —ONO2 groups in molecular structure,pentanol-3-nitraza-5-azidonitrate（PNAN）（crude product）was designed and synthesized for the first time via reaction in dimethyl sulfoxide,using 1,5-dinitrato-3-nitraza pentane（DINA）and sodium azide as raw materials The crude product was separated and purified bysilica gel column chromatography with the purity of 98.60%.The structure of PNAN was characterized by IR,1 HNMR and elemental analyses.Some physicochemical properties of PNAN were obtained by the tests.Results show that the density is 1.46 g·cm-3,decomposition temperature 172℃,glass transition temperature-41℃,viscosity19.5 mPa·s,friction sensitivity 12% and impact sensitivity 56%.
