Synthesis and Characterization of 1H-imidazolium-4,5-dinitrile Dioxides Hydrochloride
摘要
Abstract
Using 4,5-dicyanoiazole as starting material, a novel energetic compound 1H-imidazolium-4,5-dinitrile dioxides hydrochloride with total yield of 58.2% was self-designed and synthesized by addition reaction of hydroxylamine to cyanide, diazo-substitution reaction and hydrolysis reactions eliminating chlorine hydride.The structures of target compound and intermediates were characterized by IR, NMR and elemental analysis.Single crystal of the intermediate 4,5-dichloroximidoimidiazolium hydrochloride was cultured.The SHELXTL program was used to analyze the X-ray data of single crystal to get the structure parameters of crystal.Thermal decomposition property of 1H-imidazolium-4,5-dinitrile dioxides hydrochloride was studied by DSC.The results show that 4,5-dichloroximidoimidiazolium hydrochloride belongs to orthorhombic crystal system, the space group is Pna2(1), and molecular weight is 259.47 with density of 1.699 g/cm3.The exothermic reaction of 1H-imidazolium-4,5-dinitrile dioxides hydrochloride starts from 140.23℃ with two exothermic peaks at 162.73℃ and 177.73℃, and the exothermic reaction is ended at 208.48℃, showing that the structure of 1H-imidazolium-4,5-dinitrile dioxides hydrochloride is stable.关键词
