Abstract

The kinetics of the reaction of O3 with PhOH in alkaline medium has been studied. The rate of oxidation of phenol by ozone is directly proportional to the concentrations of reactants and increases in a complex manner with increase in alkali content in aqueous solution. The composition of the reaction products was investigated and it was found that dimers and oligomers of phenoxyl radicals predominate in alkaline medium. A mechanism is proposed for the process.
