Studies on Energetic (Non) Compounds. Part 21: Preparation and thermal decomposition of ring substituted dimethyl anilinium bromides

Six isomeric dimethyl anilinium bromides (DMABr) have been prepared and cha racterized by elemental and spectroscopic studies. Thermal decomposition of these salts has been studied by TG and simultaneous TG-DTA techniques. Kin etic parameters have been evaluated from isothermal TG data using contracti ng area and contracting cube equations. The decomposition pathways have als o been suggested which involves simultaneous sublimation (at lower temperat ure) and dissociative vaporization/decomposition (at higher temperature).
