The deamination reaction of[Ni(NH₃)₆]Cl₂ was studied by using the non-isothermal TG method.The data from the non-isothermal experiments were analyzed by means of ACHAR and COATS-REDFERN methods.It was found that the integral kinetic equation and differential coefficient kinetic eqution for the deamination of[Ni(NH₃)₆C]I₂ were f(α)=[-ln(1-α)]^-1,g(α)=α+(1-α)ln(1-α),activation energies were E₁=81.223 6 kJ/mol,E₂=189.634 2 kJ/mol;pre-exponential factor A₁=4.10×10⁹/s,A₂=7.02×10²²/s,and kinetic compensation effect equation ln A₁=3.519 6E₁+5.378 2;ln A₂=3.457 3E₂+4.804 5.
