%X The decomposition process of methyl N-phenyl carbamate(MPC) was studied by TG-DTG,DSC and IR techniques.It is shown that the decomposition of MPC for generating phenyl isocyanate(PI) is one step with the generation of methanol gas.Then non-isothermal decomposition kinetics of MPC was studied.Flynn-Wall-Ozawa method was used to calculate the reaction activation energy,E,through the data of DSC/TG/DTG.The kinetic parameters were calculated using five kinetic analytical methods.The result indicated that the mechanism function of MPC decomposition was G(α)=α1/3,E and the pre-exponential factor,A,of the reaction were E=20.52 kJ/mol and lgA=2.23,respectively,and the kinetic equation could be expressed as α1/3=169.82exp20.52×10~3/(8.314T)]t.
