Abstract: a kinetic study of AP-TPR-profile of silica immobilized thioanisole was carried out, resulting in a better understanding of the mechanistic behaviour of this model compound under the specified conditions. AP-TPR (Athmospheric Pressure - Temperature-Programmed Reduction) with potentiometric sulfur detection is a thermoanalytical method used to differentiate between sulfur forms in solids like coals. In this respect, sillica-immobilized thioanisole was recorded as a nonmelting calibrant. Several kinetic methods exist to analyze a heterogenous process involving a solid that is heated by a linear temperature programme. The isoconversial method can be considered as one of the most accurate. It was applied to to the AP-TPR-profile of thioanisole, showing the reduction of this compound very quickly becomes a diffusion-controlled reaction. Kinetic parameters are reported for this process under the AP-TPR-conditions.
