Abstract: Four dichloroanilinium sulphate (DCAS) and one dichloroanilinium hydrogen sulphate (DCAHS) salts have been prepared and characterized by elemental analysis and spectral data. Thermolysis of these salts has been evaluated by TG (static air), simultaneous TG-DTG (inert atmosphere) and isothermal analyses. Dynamic and isothermal TG data were used to obtain the kinetic parameters using mechanism based kinetic equations. The thermal decomposition pathways have also been suggested for both types of salts via solid-state sulphonation involving proton transfer as primary step.
