The kinetics of formation reaction of Zn(Ⅱ)、 Cd(Ⅱ)、 Hg(Ⅱ) with metamethyl tetraphenylporphyrin (H2T(m-CH3)PP) in acetone and Zn(Ⅱ) with tetraphenylporphyrin (H2TPP) in acetone or in DMF have been studied. A general mechanism was proposed and the kinetic parameters were obtained by non-linear least-squares program. The different behavior of the reaction system of Zn(Ⅱ)、 Cd(Ⅱ)、 Hg(Ⅱ) have been interpreted reasonably. The effects of temperature and solvent on the reaction rate were also investigated in this paper.
