The thermal behaviour and decomposition reaction kinetics of benzotrifuroxan (BTF) were determined by TG and DSC techniques. The kinetic parameters of the exothermic decomposition reaction in a temperature programmed mode (the apparent activation energy E(a) and pre-exponential factor A) were calculated by a single non-isothermal DSC curve. The E values calculated using the Kissinger and Flynn-Wall-Ozawa equations and integral isoconversional non-linear equations were used to check the validity of activation energy by a single non-isothermal DSC curve. The results show that the kinetic model function in integral form and the values of E(a) and A of the decomposition reaction of BTF are [-1n(1-alpha)](2/3), 109.95 kJ center dot mol(-1) and 10(8.16) s(-1), respectively. The values of Delta S(not equal), Delta H(not equal) and Delta G(not equal) of this reaction are -93.15.J center dot mol(-1)center dot K(-1), 150.72 kJ center dot mol(-1) and 153.15 kJ center dot mol(-1), respectively. The critical temperature of thermal explosion of BTF is 257.33 degrees C.
