Cation modified silicates for catalytic production of phenol from benzene

Abstract

In this work, we produced phenol directly from benzene using silicates modified with Al and Fe. The preparation of Al and Fe-silicates was done at 373 K by mixing a silicate solution with Al and Fe sources and the resulting material were dried at 373 K overnight and calcined at 823 K. The calcined materials were characterized using XRD, IR, SEEM and SBET. The oxidative properties of resulting solids (Al and Fe-silicates) were tested in the catalytic oxidation of benzene to phenol at different temperatures. The oxidation processes were followed up using HPLC and UV-Vis Spectrophotometry.
