Since some success has already been achieved in the reduction of muzzle flash by the incorporation of compounds containing a high percentage of nitrogen such as dicyandiamide and nitroguanidine in propellent compositions it was considered desireable to extend this approach and to investigate other substances with comparatively high nitrogen content. The substitution of hydrazine radicals for amino radicals in ammonia derivatives produces substances with considerably higher nitrogen content. Consequently a large portion of the compounds studies were chosen so as to form member of homologous series with a progressive increase in the number of hydrazine groups. It was found that progressive substitution of hydrazine radicals for amino and imino groups in guanidine causes, within the homologous series, an increase in sensitivity to impact, in brisance and in sensitivity to initiation, and a decrease in explosion temperature. The stability of these carbonic acid derivates, however, was not affected by the presence of hydrazine radicals. It was noted that the stability increased qualitatively, in this series, the higher the melting point.
