Thermal Degradation Kinetics of N,N'-Di(diethoxythiophosphoryl)-1,4-phenylenediamine
چکیده انگلیسی
The non-isothermal degradation kinetics of N,N'-di(diethoxythiophosphoryl)-1,4-phenylenediamine in N2 was studied by TG-DTG techniques. The kinetic parameters, including the activation energy and pre-exponential factor of the degradation process for the title compound were calculated by means of the Kissinger and Flynn-Wall-Ozawa(FWO) method and the thermal degradation mechanism of the title compound was also studied with the Satava-Sestak methods. The results indicate that the activation energy and pre-exponential factor are 152.61 kJ/mol and 9.06 × 1014 s-1 with the Kissinger method and 154.08 kJ/mol with the Flynn-Wall-Ozawa method, respectively. It has been shown that the degradation of the title compound follows a kinetic model of one-dimensional diffusion or parabolic law, the kinetic function is G(α)=α2 and the reaction order is n=2.
