Table-1: Basic data for the intense exothermic decomposition process of ACOF.
To explore the reaction mechanism of the intense exothermic decomposition process of ACOF and obtain the corresponding kinetic parameters [apparent activation energy (E a /kJmol [?]1 ), pre- exponential constant (A/s [?]1 )] and the most probable kinetic model function, the DSC curves at the heating rates of 2.5, 5.0, 10.0 and 15.0 Kmin [?]1 were dealt with the mathematic means, and the temperature data corresponding to the conversion degrees ((alpha)) were found.
Therefore, we conclude that the reaction mechanism of the intense exothermic decomposition process of ACOF is classified as Avrami-Erofeev equation G((alpha)) = [-ln(1-(alpha))] 1/2 , f((alpha)) = 2(1-(alpha))[-ln(1-(alpha))] 1/2 .

The entropy of activation ((delta)S [?] ), enthalpy of activation ((delta)H [?] ) and free energy of activation ((delta)G [?] ) of the main exothermic decomposition reaction of ACOF corresponding to T = T po , E a = E k and A = A k are obtained by Eqs.
The period of validity of the ACOF could be determined by the following equation:
The period of validity for ACOF is 37.29 thousand years, indicate that ACOF is very stable under 298.15 K.
ACOF was prepared and purified by a reported method .
The specific heat capacity of ACOF was determined with a continuous C p mode on a Micro- DSCIII apparatus (Seteram, France) under atmospheric pressure, heating rate, 0.15 Kmin [?]1 , sample mass, 285.40 mg; atmosphere, N 2 ; and the specific heat capacity determined for ACOF is C p (Jg - 1 K -1 ) = 1.6041x10 -7 T 3 - 1.6121x10 -4 T 2 + 5.6467x10 - 2 T - 5.6373 (283K less than T less than 354K).
