Abstract

While stored at various temperatures between 65°C and 90°C, several double base propellants with the Same composition differing only in the stabilizer, were aged artificially to the onset of autocatalytic decomposition. A correlation between the temperature and the storage period has been established for the results obtained at the respective temperatures.

Moreover, studies were carried out on the chromatographic analysis of stabilizer reaction products of the type occurring in particular in propellants with diphenylamine, 2‐nitrodiphenylamine, acardite I, acardite 11, and ethylcentralite as a result of storage at elevated temperatures due to reactions with the decomposition products of nitric acid esters.

It has been shown that continuing aging of the propellant gives rise to stabilizer reaction products which are quite characteristic of the respective aging condition. These reaction products may be used as a criterion for different stages of aging within the shelflife of solid propellants.
