Abstract
The invention relates to an energetic active composition comprising a dihydroxylammonium salt or diammonium salt of 5,5′-bistetrazole-1,1′-diol, 5,5′-bistetrazole-1,2′-diol or 5,5′-bistetrazole-2,2′-diol or a mixture of at least two of these salts.
Claims20
5,5′-Bistetrazolediol or salt thereof, wherein the 5,5′-Bistetrazolediol is 5,5′-Bistetrazole-1,2′-diol or 5,5′-Bistetrazole-2,2′-diol and the salt is dihydroxylammonium salt or diammonium salt.
An energetic active composition comprising a dihydroxylammonium salt or diammonium salt of 5,5′-bistetrazole-1,1′-diol, 5,5′-bistetrazole-1,2′-diol, or 5,5′-bistetrazole-2,2′-diol, or a mixture of at least two of these salts.
A process for preparing a dihydroxylammonium salt or diammonium salt of 5,5′-bistetrazole-1,1′-diol, 5,5′-bistetrazole-1,2′-diol, or 5,5′-bistetrazole-2,2′-diol, or a mixture of at least two of these salts, comprising the following steps:
- a) oxidizing 5,5′-bistetrazole to give a mixture of 5,5′-bistetrazole-1,1′-diol, 5,5′-bistetrazole-1,2′-diol, and 5,5′-bistetrazole-2,2′-diol, or promoting the isomerization of diazidoglyoxime to 5,5′-bistetrazole-1,1′-diol or a 5,5′-bistetra-zole-1,1′-diolate;
- b) incubating one or more reaction product from step a) with hydroxylamine, hydroxylammonium ions, ammonium ions, or ammonia in aqueous solution;
- and
- c) isolating the resultant precipitate.
