The role of the methyl ketones in oscillating reactions of the Belousov-Zhabotinsky (BZ) type is to eliminate bromine through an enolization process, but its importance in the dynamic of the reaction depends upon the organic compound that is used as substrate. This work shows that in a binary mixture of methyl ketones every ketone acts independently, but with an additive effect in the dynamics of the BZ reaction. The results obtained are supported by numerical simulations based upon the mechanisms for both reactions.
