Аннотация:A detailed kinetic study has been made of the hydroxylation of phenol by hydrogen peroxide with a previously prepared iron sulfate-pyrocatechol complex as the catalyst. By means of the initial rate method, a model has been obtained, giving an adequate description of all of the observed relationships within the intervals of variation of initial concentrations that were investigated. phenol 0.25-3 M, hydrogen peroxide 0.25-3 M.
