1,4‐Diformyl‐2,3,5,6‐Tetranitratopiperazine: A New Primary Explosive Based on Glyoxal

Abstract

Abstract In the present work we describe synthesis and properties of 1,4‐diformyl‐2,3,5,6‐tetranitratopiperazine. The 1,4‐diformyl‐2,3,5,6‐tetranitratopiperazine turned out to be a powerful highly energetic compound. Its physical and chemical properties were investigated by theoretical as well as experimental methods. The detonation energy of 1,4‐diformyl‐2,3,5,6‐tetranitratopiperazine was determined to 5376 kJ/kg or 93% compared to HMX. Molecular and crystal structure of 1,4‐diformyl‐2,3,5,6‐tetranitratopiperazine was elucidated by single crystal X‐ray diffraction analysis. An interesting feature of the title substance, its rotamer equilibrium, was investigated by 2D NMR methods.
