Five salts of dichloroanilinium chloride (DCACl) were prepared and characterised by elemental and spectral studies. Thermal decomposition of these salts was investigated by simultaneous TG-DTG-DTA and isothermal TG. Kinetic parameters have been evaluated from the model fitting and model free isoconversional methods. It has been observed that simultaneous sublimation/decomposition processes are involved during the thermal decomposition of DCACl.
