摘要

The kinetics of the reaction of Ph_2NH (A) with S_2O_8~(2-) (P) under O_2 free condition was studied in homogenous medium using H_2O+dioxane (33 percent by volume) solution in presence of the PDS anion active micelles. In absence of PDS micelles, Ph_2NH oxidation is consecutive the final product being diphenylbenzidine violet. When PDS micelles are present, the over-all reaction rate decreases. At (E-30)_0 >= 0.16 M, the reaction is stopped at the stage of tetraphenyl-hydrazine (TPhH) formation, which leads to slowing down of the over-all rate of S_2O_8~(2-) consumption. This fact has been explained assuming that water soluble S_2O_8~(2-) and oil-soluble TPhH are localized in different loci in the reaction medium. The distribution coefficient (P_A) of the reductant between micellar and water as well as water-EtOH-dioxane solutions has been determined.
