Abstract

Abstract: Aseries of α-Fe₂O₃catalysts inlaid in small pore resin was synthesized and used in the reaction of phenol hydroxylation with H₂O₂The amount of Fe inlaid was measured by atomic absorption. The results of Mssbauer spectra indicated that α-Fe₂O₃was the main state, and the average diameter was smaller than₅nm. The conversion of phenol was about 24%, the selectivity of diphenol was higher than 90%, and the conversion of H₂O₂almost reached 100% at the 3:1 molar ratio of phenol to H₂O₂These results reached the values of Enichem's technology in Italy.

Key words: Small pore resin, α-Fe₂O₃, Nanometer particle, Hydroxylation of phenol with hydrogen peroxide, Dihydric phenols
