Synthesis and Properties of 4-Amino-2,6-bis(5-amino-1 H-tetrazol)-3,5-dinitropyridine
摘要
Abstract
A novel thermally stable energetic material,4-amino-2,6-bis(5-amino-1 H-tetrazol)-3,5-dinitropyridine(ABDP) was first synthesized via two-step reactions of nitration and condensation reaction using 4-amino-2,6-dichloropyridine as a raw material with a total yield of 36％,and its structure was characterized by nuclear magnetic resonance (NMR),mass spectrum (MS) and elemental analysis.Condensation reaction of 3-amino-1,2,4-triazole or 5-amino-1 H-tetrazole and 4-amino-2,6-dichloro-3,5-dinitropyridine was investigated.Its thermal properties were studied by thermogravimetry(TG) and differential scanning calorimetry(DSC).Results show that similar nucleophilicity occurs at primary amine and secondary amine of 3-amino-1,2,4-triazole,but secondary amine in 5-amino-1 H-tetrazole has higher nucleophilicity than that of primary amine.ABDP has a thermal decomposition peak at 323 ℃ accompanied with 94％ mass loss.The detonation velocity and detonation pressure of 4-amino-2,6-bis(5-amino-1 H-tetrazol)-3,5-dinitropyridine are predicted by Rothstein's method with the values of 8823 m · s-1 and 36.72 GPa,respectively.关键词
