Abstract
Ferric trisacetylacetonate has been deposited within the zeolite MCM-4 1 and the product characterized by XRD and IR. In water at pH 7 it cat alyzes the oxidation of phenol by H2O2, giving 58% conversion in 1 h a t 50 degrees C: products are catechol (66%), hydroquinone (27%) and be nzoquinone (7%). Other oxidants and solvents are much less effective. UV-VIS spectra suggest a radical substitution mechanism, and a polluti on-free process for phenol hydroxylation is now possible.
