The photolysis of aerated aqueous solutions of 4-chlorophenol in the presence of Ru(bpy)2+/3 and peroxydisulphate has been followed by UV/visible absorption specrroscopy, and reveals a relatively rapid oxidative decomposition of the phenol. Confirmation of the formation of benzcquinone and dihydroxybenzene as the principal products comes from product separation and spectroscopic characterization, HPLC, and TLC. 4-Chlorocatechol is also produced, while the main inorganic products are shown to be chloride and sulphate ions. Ru(bpy)2+/3 is regenerated in the reaction scheme, making this an overall catalytic process. Prolonged irradiation leads to further degradation into CO2 and HCl. From the study of the kinetics of the reactions and considerations of literature data, a mechanistic scheme is presented. VCH Verlagsgesellschaft mbH, 1996.
