Resumo

The purpose of this work was to study the kinetic depletion of stabilizers 2-NDPA in double-base propellants. Topics relatives at analytic method utilized and interferences in kinetic of depletion of stabilizers by presence of nitroglycerine and lead salicylate are presented. The kinetics parameters of depletion of stabilizers were determined by High Performance Liquid Chromatography (HPLC). The experimental data were adjusted to a pseudo-first kinetic model. The activation energy (Ea) and the pre-exponential factor (A) calculated were (1.22 ± 0.42) 102 kJ mol -1 and (1016 ± 106) day-1, respectively.
