| Abstract: | The thermal decomposition of dicumyl peroxide was studied in the flow air atmosphere by thermogravimetry-differential thermogravimetry(TG-DTG) method.The non-isothermal kinetic data were analyzed by the Starink method,the Madhusudanan-Krishnan-Ninan(MKN) method and the Achar-Brindley-Sharp-Wendworth(ABSW) method.The possible reaction mechanisms were suggested by comparing with the kinetic parameters.The thermal decomposition mechanism of dicumyl peroxide in nitrogen was controlled by interface reaction R3.T... |
