| abstract |
The present invention is a process for making a 1,2,4-triazolo[4,3-a][1,3,5]triazine-3,5,7-triamine, acid salt and a process for neutralizing the acid salt to make 1,2,4-triazolo[4,3-a][1,3,5]triazine-3,5,7-triamine. 1,2,4-triazolo[4,3-a][1,3,5]triazine-3,5,7-triamine can be used as a precursor for ingredients in propellants, explosives, pyrotechnics, gas generators, pharmaceuticals, and azo dyes. The general process involves ring closure of 2,4-diamino-6-hydrazino-s-triazine with an acid and a chemical of the general formula RCN where the R comprises a leaving group, then neutralizing said acid. |
