Mechanism of solid/liquid interfacial reactions. Atomic force microscopy studies of the self-passivating reaction between solid p-chloranil and aqueous phase N,N-dimethylphenylenediamine

Abstract:

The reaction between solid p-chloranil and alkaline aqueous solutions of dimethylphenylenediamine is shown to be self-passivating owing to the formation of insoluble product at the reacting interface. In situ atomic force microscopy imaging of the reaction occurring at (010) surfaces of single crystals of p-chloranil show that the nucleation of the overgrowth is progressive and that its coverage, S, follows the time (t) dependence S(t) = 1 - exp(-k3t3), where k3 is a rate constant.
