Studies on the thermal decomposition of ferric acetate

Abstract

The thermal decomposition of ferric acetate,Fe(CH3COO)3, has been investigated using thermogravimetry (TG), differential thermal analysis (DTA), the conventional method involving the measurement of the volume of gaseous products evolved during decomposition and the X-ray diffraction technique. Analysis of the kinetic data obtained both by the conventional method and the polythermal decomposition using thermogravimetry gave nearly the same activation energy for the decomposition of ferric acetate. The endothermic peaks at 278 and 328°C appear to be due to the decomposition accompanied by the desorption of acetone and carbon dioxide, respectively.
