| Abstract: | The single crystals of 1-methyl-4,5-dinitroimidazole(4,5-MDNI)were obtained by slow evaporation of the solvent at room temperature and the crystal structure was determined by a four-circle X-ray diffractmeter.The crystal structure is orthorhombic with space group Pna2(1)/n,a=8.412 3 ,b= 12.646 ,c= 6.562 7 ,V=698.2 3,Z=4,D=1.637 g/cm3,F(000)=352.The results show that the density determined by density bottle is 1.542 g/cm3 and the detonation velocity determined by high speed rotating mirror framing camera is 7 093 m/s.The 50% drop height of impact sensitivity H50 is 87.5 cm using a WL-1 drop hammer-meter.The DSC-TG technique was used to investigate the thermal behavior of the title compound,showing that the title compound is a low melting point explosive with good thermal stability,insensitivity and high energy and is expected to become a new melt-cast to replace TNT. |
