Abstract: Three perchlorate salts of pyridine have been prepared and characterized by gravimetric and elemental analyses. Thermogravimetry (TG) and differential thermal analysis (DTA) have been carried out in static air, to examine the thermal decomposition process of these salts. Isothermal TG of these salts have been done to evaluate the kinetics of thermal decomposition in the temperature range 290-410oC using both model fitting and isoconversional methods. Isoconversional method has been found to be superior over conventional model fitting method and is able to describe the decomposition process of these salts. Moreover, Explosion delay (DE) measurements have been carried out to investigate the response of the salts under the condition of rapid heating.
