ABSTRACT:
The compound 2,4-dinitroimidazole is highly insensitive towards impact and its thermal stability is excellent. The calculated detonation properties results indicate that its performance is about 30% better than TATB. It can be prepared easily with good yield starting from inexpensive starting materials. Results from impact sensitivity, friction sensitivity time-to-explosion temperature and vacuum stability tests indicate that 2,4-dinitroimidazole is less sensitive than both RDX and HMX. Its good oxygen balance and measured heat of formation data of this material indicate that its propellant performance is good.
