Abstract: A one-pot process for preparing ammonium and hydroxylammonium salts of bis 5,5?-tetrazole-1,1?-dihydroxide, specifically, diammonium bis 5,5?-tetrazole-1,1?-diolate (ABTOX) and dihydroxylammonium 5,5?-bistetrazole-1,1?-diolate (TKX-50). The process requires the reaction of sodium azide, dichloroglyoxime, HCl in dioxane solution to form bis 5,5?-tetrazole-1,1?-dihydroxide and treating this product with either ammonium chloride to produce ABTOX or hydroxylamine hydrochloride to produce TKX-50.

Abstract: A novel method for preparing 3-chlorocarbohydroxymoyl-4-nitro-1,2,5-oxadiazole by reacting 4-amino-3-chlorocarbohydroxymoyl-1,2,5-oxadiazole with H2O2 and a tungsten based catalyst and use of the prepared 3-chlorocarbohydroxymoyl-4-nitro-1,2,5-oxadiazole for synthesizing 3,4-Bis(4-nitro-1,2,5-oxadizaol-3-yl)-1,2,5-oxadiazole-N-oxide (DNTF).

Abstract: A lead-free primer energetic composition including Cyanuric Triazide (60%), Tetracene (5%), Barium Nitrate (20%) and Antimony Trisulfide (15%) is produced. The lead-free primer energetic composition is used to construct a primary detonator including a transfer charge of Cyanuric Triazide, which produces a further initiation train that may subsequently detonate a secondary explosive, i.e., HDX, RDX, or a pyrotechnic device.

Abstract: 1-Methyl-2,4,5-Trinitroimidazole is synthesized starting from 4-nitroimidazole using stepwise nitration method and further methylation using Dimethylsulphate. It is relatively insensitive to impact and its thermal stability is excellent. The calculated detonation properties indicate that its performance is about 30% better than TATB. It can be prepared easily, with reasonable yield, starting from commercially available Imidazole. Results from impact sensitivity, friction sensitivity, time-to-explosion temperature and vacuum stability tests indicate that it is less sensitive than both RDX and HMX. The good oxygen balance and measured heat of formation data of this material indicate that its propellant performance should be good.
