Under linear temperature increase condition thermal behaviors, mechanismfunction and kinetic parameters of thermal decomposition of 2,6-dinitrophenol obtained with a model CDR-1 instrument with the sealed cell of stainless steel are reported. The data are fitted to the integral, differential and exothermic rate equations by linear least-squares, iterative, combined dichotomous and leastsquares methods, respectively. The apparent activation energy, pre-exponential constant, reaction order and probable mechanism function (integral form) of thermal decomposition reaction of 2,6-dinitrophenol obtained by the logical choice method are 134±9 kJ mol~(-1), 10~(9.17±0.77)s~(-1), 0, and a respectively.
