Pages: 503-507
Year: Issue:  6
Journal: Chinese Journal of Energetic Materials

Abstract: 3-Cyano-4-nitrofuroxan was synthesized from dicyanopropane via diazotisation,addition,cyclization and oxidation reactions,and its structure was characterized by IR,13C NMR and 15N NMR and elemental analysis.The yields of cyclization and oxidation reactions are 55.1% and 83.6%,respectively.In the 13C NMR,the chemical shifts were assigned by comparing with 3-cyano-4-nitrofurazan,which further confirm the configuration of 3-cyano-4-nitrofuroxan.The bond order,density,enthalpy of formation and detonation parameters of 3-cyano-4-nitrofuroxan were calculated theoretically.Results show that the minimum bond order are N(1)-O(4)(0.84) and C(6)-N(9) (0.91),the density is up to 1.74 g · cm-3,the enthalpy of formation is 352.6 kJ · mol-1,and the detonation velocity and detonation pressure are 8352 m · s-1 and 30.9 GPa,respectively.
