Differential and Integral Isoconversional Non-linear Methods and Their Application to Energetic Materials.III.Non-isothermal Decomposition Reaction Kinetics of Benzotrifuroxan

摘要

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 pro-grammed mode(the apparent activation energy Ea 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 inte-gral 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 Ea respectively.The critical temperature of thermal explosion of BTF is 257.33 ℃.
