Abstract: The present invention provides a method for the preparation of an insensitive high enthalpy explosive Dihydroxylammonium 5,5?-bistetrazole-1,1?-diolate (TKX-50) in the presence of N,N-dimethylformamide, N,N-dimethylacetamide, or N-Methyl-2-pyrrolidone as a solvent via a four-step, one-pot reaction route to obtain a final product after four reaction steps. The more dangerous intermediate diazidoglyoxime may be solved by the one-pot method without the need of isolation. Further, the cyclization reaction is carried out in the presence of dropwisely added concentrated sulfuric acid to replace hydrochloric gas so no hydrochloric gas generator is needed to greatly reduce the amount of waste acid so as to effectively reduce the cost by avoiding using hydrochloric gas steel cylinders which require much safety equipment.
