Under the condition of 35.0 ± 0.1 ℃ and ionic strength of 0.1 mol·L-1NaClO4, the effect of meso-tetraphenyphenolporphyrin and Cu in N, N’-dimethylformamide solution Bit Reaction Kinetics. According to the association state of CuCl2 in this system and the influence of hydrogen ion concentration on the reaction rate, the kinetic equation of copper porphyrin formation reaction was obtained. The activation parameters of this reaction were measured. The results show that the reaction follows the mechanism of association dissociation and the dissociation of the active intermediate is the rate-determining step of the reaction
