Description

It was made quantitatively clear that the oxidative polymerization process of aniline by S2O82- ion in a highly concentrated hydrochloric acid aqueous solution was a clock reaction. It was strongly dependent on the concentration of S2O82- ion at the start time of the clock reaction. The rate-determining process of the reaction was a one-electron transfer process from C6H5NH2 to S2O82- ion. A possibility was strongly indicated that the strong magnetic field impression effect for this electron-transfer process acted as an inhibitive effect. Moreover, it became clear that the strong magnetic field impression did not influence the formation process of polyanilin. Also, it was indicated that the formation of polyaniline was suppresed by the reaction of the aniline radical with the dissolved oxygen.
