Abstract

The invention discloses a 3,4-di(3',5'-dinitryl-4'-methyl phenyl) furoxan compound, the structural formula of which is shown in the specification. The compound is mainly applied to energetic materials.

Description

technical field [0001] The invention relates to a 3,4-bis(3',5'-dinitro-4'-methylphenyl)furazan compound. Background technique [0002] Oxyfuroxan compounds are an important class of energetic compounds, and the intramolecular furoxan ring as an explosive group can provide relatively higher energy density. Substituting a furazanyl oxide for a nitro group can increase the density of the compound by 0.06-0.08g / cm 3 , the detonation velocity is increased by about 300m / s; furazan oxide derivatives as energetic additives can improve the oxygen balance of the system and increase the detonation pressure; in addition, the furazan oxide ring can also endow its derivatives with ring tension and high standard enthalpy of formation. The introduction of aromatic rings into the structure of furoxan can endow it with better thermal stability. The polynitroaryl-substituted arylfuroxan compounds combine nitroaryl and furazanyl groups, which can not only increase the energy density, but als...
