Synthesis and Properties of C8H24N4(ClO4)4 and C8H24N4(NO3)4∙2H2O
摘要
Abstract
Two new explosives,C8H24N4(ClO4)4 and C8H24N4(NO3)4∙2H2O,were prepared from 1,4,7,10-tetranitrocyclododec-ane by salt formation with nitric acid and perchloric acid respectively.The structures,thermal properties,and detonation perfor-mances of the target products were studied through single crystal X-ray diffraction,infrared spectroscopy,elemental analysis,dif-ferential thermal analysis,thermogravimetric analysis,and EXPLO 5.0 program.Results indicate that C8H24N4(ClO4)4 crystallizes in the orthogonal crystal system,Pcc2 space group with a crystal density 1.968 g∙cm-3.The crystal of C8H24N4(NO3)4∙2H2O is a di-hydrate with a crystal density of 1.642 g∙cm-3,which belongs to the monoclinic crystal system P21/n space group.The thermal de-composition peak temperatures of C8H24N4(NO3)4∙2H2O and C8H24N4(ClO4)4 are 293.2℃and 284.1℃,and activation energies are 131.76 kJ·mol-1 and 195.18 kJ·mol-1,respectively.Compounds C8H24N4(NO3)4∙2H2O and C8H24N4(ClO4)4 exhibit excellent detonation properties,showing very promising performance values(C8H24N4(NO3)4∙2H2O,D=8058 m∙s-1,p=24.0 GPa;C8H24N4(ClO4)4,D=8680 m∙s-1,p=36.2 GPa).Moreover,the impact sensitivities of C8H24N4(NO3)4∙2H2O and C8H24N4(ClO4)4 are 36 J and 33 J,respectively,and their friction sensitivities are higher than 360 N.关键词
