Hydroxylation of Phenol over M-MCM-48

The synthesis and characterization of M-MCM-48 (M = Si, Ti, V, Cr, and Mn) materials have been carried out. These systems promote hydroxylation of phenol with 30% H2O2 and the hydroxylation activity is highest for Ti-MCM-48. Water appears to be a better solvent than acetone and acetonitrile.
