ABSTRACT:
A one-pot process for making energetic cast cured binders making di-tetrazoles to produce di-functional di-tetrazole diols for making tetrazole base polymers. Embodiments of the present invention relate generally to a process for preparation of a di-functional monomer including reacting an effective amount of nitrile(s) with inorganic azide and a divalent zinc salt in a first solvent, cooling to room temperature producing a di-tetrazole, purifying said di-tetrazole by recrystallization in a second solvent, and reacting an effective amount of said purified di-tetrazole with a third solvent, a soluble reversible or non-reversible base, and 2-chloro-ethanol, cooling to room temperature producing a di-tetrazole diol and is prepared in a one-pot process. Embodiments of the present invention further include the monomers produced by the one-pot process described herein.
