Abstract / Description of output

The reduction of halothane at pH 13 has been studied on a variety of electrode materials. The overall reaction has been shown to involve two electrons with the production of a bromide ion. The first electron transfer is the slowest electrochemical step. Using Tafel analysis of the convoluted cyclic voltammetric and rotating-disc data, this is found to be electrochemically irreversible. The chemical steps are fast and never rate limiting. In contrast with previous mechanistic proposals, there is no evidence of specific electrode-substrate interaction or adsorption of reactant or products. An overall reaction mechanism consistent with these observations is presented.
