Kinetik und Mechanismen beim photochemischen Abbau von Fluorphenolen

The results of a study of the photolytic degradation of mono- and difluorophenols as a function of oxidation agent and temperature are reported. The effects of the position of fluorine are discussed. Fluorinated aromatic compounds have been mineralized to CO₂, fluoride, acetate and formate by irradiation (l=254nm) over various intermediate steps. The degradation of fluorophenols apparently followed first-order kinetics. A proposed degradation pathway for the photolytic oxidation of fluorophenols is presented. A complete mineralization as generally proposed in the literature cannot be supported by our results.
