二乙基叠氮铝的分子结构和性质

MOLECULAR STRUCTURE AND PROPERTIES OF DIETHYLALUMINUM AZIDE

作者在本刊报道过二乙基叠氮铝（ＤＥＡＡ）的合成，在此基础上，本文进一步介绍了合成溶剂的选择和分离条件。通过分子结构的测定和主要性质的研究，在不同压力和温度条件下蒸馏的结果都证明，ＤＥＡＡ是一个热稳定性优良的三聚体化合物，不仅可用作自燃并由燃烧转爆轰的燃料。

Based on the preceding report about DEAA synthesis, the solvent choice for synthesis reaction,distillation conditions and the main properties are further described. The molecular structure of DEAA was determined by means of infrared spectrum, 1 H NMR and other methods. The results identify that DEAA is a trimer with stable six membered ring structure. The behavior of DEAA in distillation under different temperature and pressure agrees with the results of its structure analysis.It can be concluded that DEAA is a compound with acceptable thermal stability,which could be used as a self ignitable pyrophoric agent and a promising precursor used to prepare superhard material alumimum nitride (AN).
