| Abstract: | The thermal decomposition kinetics of rosiglitazone maleate was studied by the technique of differential thermal analysis. The kinetic parameters of thermal decomposition of rosiglitazone maleate were calculated by the Kissinger’s equations. The results were in good agreement .The reaction order of thermal decomposition was the first. The activation energy (E), frequency factor (A) and the correlated coefficient of kinetic equation were 127.7 kJ/mol, 2.04×108 S-1 and 0.992 5 respectively. |
