General description
1,4-Cyclohexanedione(CHD) undergoes uncatalyzed oscillatory reactions during oxidation by acidic bromate in nitric acid and sulphuric acid solution. It reacts with acidic bromate to form 1,4-dihydroxybenzene which on further oxidation and bromination yields 1,4-benzoquinone and bromoorganics.
Application
1,4-Cyclohexanedione has been used to study the influence of visible light on the bromate-1,4-cyclohexanedione-ferroin oscillating reaction.
