Synthesis and Properties of N2,N6-Dimethyl-N2,N4,N6,3,5-Pentanitro-2,4,6-Pyridinetriamine
摘要
Abstract
A pyridine energetic molecule,N2,N6-dimethyl-N2,N4,N6,3,5-pentanitro-2,4,6-pyridinetriamine(NNDP),has been synthesized in two steps from 4-amino-2,6-dichloropyridine.The process was found to be effective and simple.The structure of this compound is characterized by 1H and 13C NMR,FT-IR and DSC.The crystal structure of this compound is characterized by X-ray single crystal diffraction.Results shows that compound NNDP belongs to the monoclinic space group P 21/c,a=16.3215(17)Å,b=7.9819(8)Å,c=13.1954(13)Å,V=1712.3(3)Å3,α=90(6)o,β=95.093(3)o,γ=90(7)o,Z=4.The presence of multiple ni-tro and nitramine groups contributes to a low decomposition temperature.Its detonation performance was predicted using EXP-LO5,and sensitivity testing was conducted using the BAM standard method.It was found that the detonation performance and im-pact sensitivity of NNDP(D=8762 m·s-1,p=34.5 GPa,IS=7.7 J)are comparable to those of RDX.关键词
