| Abstract: | The thermal decomposition processes taking place in the solid-state racecadotril have been studied in air using TG-DTG/DTA and DSC techniques. TG-DTG/DTA and DSC curves showed that the decomposition proceeded through a well-defined step in air with the melting point of 77.4 ℃. The activation energies were calculated through the Friedman, Flynn-Wall-Ozawa and ASTM E698 methods, and the possible conversion functions were estimated through the multiple-linear regression method. |
