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