Using a multi -temperature artificial ageing testing apparatus and a standard method of determining the effective centralite/stabilizer content, the effective centralite/stabilizer content for varying time period in propellants heated at 95 degrees C, 90 degrees C, 85 degrees C, 75 degrees C and 65 degrees C was measured. Bethelot's equation and Semenov's equation in the temperature range of 65-95 degrees C for 81 propellants were established. The safe storage life at 30 degrees C, kinetic parameters [the apparent activation energy (E) and the pre-exponential constant (A)] and isolife temperatures obtained from the established equations and the activation energy (E-alpha=0.5) obtained by integral isoconversional non-linear method for 81 propellants: single-base gun propellants (DF-01-DF-16), double-base gun propellants (SF-01-SF-13), tri-base gun propellants (SG-01-SG-02), nitramine gun propellants (GSF-01-GSF-18), double-base propellants (ST-01-ST-13), and composite modified double-base propellants (GST01-GST-19), were given. Information was obtained on the effective centralite/stabilizer consumption reaction and the kinetic compensation effect.
