Abstract

Some uncatalyzed bromate oscillators with p-substituted phenol derivatives as the organic substrates when perturbed with chloride ions show a remarkable behavior, namely, a sudden transition, at a well-defined threshold temperature, from the non-oscillatory to the oscillatory state, and back. The high sensitivity of the reacting systems towards chloride ion perturbation and the conditions for the occurrence of the phenomenon are described.
