Abstract:

The kinetic studies on the axial coordination reaction of Co(Ⅱ)-2,9,16,23-tetracaboxyphthalocyamine with 2-mercaptoethanol in aqueous solution were studied by stopped flow method. A general mechanism was proposed and the kinetic parameters were obtained by non-liner and liner least-squares program. The effects of temperature and pH on the reaction were investigated in this paper.
