Dynamics of bromate oscillators with 1,4-cyclohexanedione in a continuously fed stirred tank reactor

The dynamics of the bromate-1,4-cyclohexanedione reaction and its ferroin catalyzed version in a continuously fed stirred tank reactor are reported. In the ([Br−]0, [H2SO4]0) and ([Br−]0, [ferroin]0) planes steady-state bistability and oscillations are observed. Close to the upper [Br−]0 limit of the oscillatory domain the oscillations become aperiodic. By increasing the [ferroin]0 the characteristic of the oscillations switches from ‘uncatalyzed’ to ‘catalyzed’-type. Additionally, the effects of the bromide ions and ferroin on the batch dynamics are investigated.
