叠氮二乙基铝合成方法的改进

MODIFIED SYNTHESIS OF DIETHYLALUMINIUM AZIDE

叙述了新型含能材料叠氮二乙基铝（ＤＥＡＡ）的结构、性质、合成方法以及可能的应用前景，对以叠氮化钠、氯化二乙基铝为原料合成叠氮二乙基铝的方法进行了研究，对Ｐｒｉｎｃｅ等人的合成方法进行了较大的改进，使收率从５４％提高到７５％，并顺利地进行了减压蒸馏，还测定了样品的某些基本性质和红外光谱。

The structure,properties,synthesis and application of diethylaluminium azide(DEAA),are reviewed.The preparation method of DEAA from sodium azide and diethylaluminium chloride was modified in reactant ratio,reaction time and temperature,and the yield was increased from 54% up to 75% compared with that reported in the literature. Furthermore,DEAA was smoothly distillated at 100～108℃ under a pressure of 266.6Pa.The final product was identified by infrared spectra and some properties were analysed as well.
