Abstract:

The inhibiting effect of ammonium salts, such as ammonium carbonate, oxalate, citrate, tartrate or fluoride, and a reducing agent, such as diphenylamine on the burning rate of ammonium nitrate or ammonium perchlorate was investigated. It was thought that the effect of easily dissociating ammonium salts would consist of shifting the equilibrium of the reaction to the left, while the effect of diphenylamine would be either a reduction or a binding of the acid formed in the dissociation, thus inhibiting the further oxidation of ammonia. This assumption was verified experimentally by the combustion of ammatol 8020 taken instead of pure ammonium nitrate which does not burn in the bomb or ammonium perchlorate with or without the additives mentioned above, taken in the amount of 5 the combustion took place at varying pressures up to 1000 atm in a constant pressure bomb.
