Effect of mixed methyl ketones on the catalyzed resorcinol based oscillatory reaction at different temperatures

The present investigation establishes a comparative trend on the single, binary and ternary reaction systems having resorcinol as main substrate, inorganic bromate as oxidant and different metal ions as catalysts. However, in binary system, acetone has been added (v/v) to the skeletal (single) reaction system as co-substrate and in the ternary system, acetone with butanone, pentanone; hexanone and acetylacetone have been added (v/v) to the skeletal system in order to monitor the oscillatory parameters in presence of mixed methyl ketones at different temperatures. It is found that the temperature; the enolization constant and the hydrophobic interactions influence the oscillatory behavior as well as the formation of the end products in both binary and ternary reaction systems under investigation. The interpretation of the kinetic data revealed that the rate of bromination reaction increases with a decrease in the enolization constants of methyl ketones leading to a decrease in the time period of the oscillations.
