The system iodate‐peroxide‐manganese(II)‐butanone is a member of the Briggs–Rauscher set of oscillators. The stoichiometry and variation of the oscillation period with concentration for each component is studied under batch conditions. The system is simulated using the skeleton mechanism of earlier workers and reproduces the observed variation in oscillation period. Examination of the roles of the reaction steps shows that there are significant differences from those found using malonic acid. Iodine is stored during the low iodide regime and utilized during the high iodide regime, and different overall reactions occur during the two regimes. © 1994 John Wiley & Sons, Inc.
