Abstract: The present invention relates to functional group-protected diazidoglyoxime (DAG), a method of synthesizing the same, and a method of synthesizing TKX-50 using functional group-protected DAG. Insensitive-DAG with enhanced insensitivity, instead of sensitive DAG, may be synthesized to reduce risks of processes and harmfulness arising from threats of explosion and fire accidents caused by impact, friction and static electricity, and thus it is possible to stably synthesize functional group-protected DAG.

Abstract: The present invention relates to a method for preparing dihydroxyammonium 5,5′-bistetrazole-1,1′-diolate. The method for preparing dihydroxyammonium 5,5′-bistetrazole-1,1′-diolate, according to one embodiment of the present invention, comprises the steps of: synthesizing 5,5′-bistetrazole-1,1′-diol dihydrate (1,1′-BTO) from ditetrahydropyranyl diazidoglyoxime (THP-DAG) by using a hydrochloric acid (HCl) solution in a first solvent; and reacting 1,1′-BTO with an amine solution so as to neutralize same and, simultaneously, obtaining dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate (Thomas Klapotke explosive-50, TKX-50).
