Oxidation of benzyl alcohol to benzaldehyde over MnOx/sepiolite catalysts

Abstract

MnOx/sepiolite catalysts were synthesized by precipitation method accompanied by the calcination at 410°C. The prepated solids have been characterized by XRD, SEM, TPR-H₂. MnOx particles were deposited on the surface of the sepiolite fibers and act as active sites for the oxidation of henzyl alcohol using ten-butyl hydroperoxide (TBHP) as an oxidizing agent. The catalysts showed a good conversion of benzyl alcohol to benzaldehyde at 60°C. The intluence of the reaction time and reaction temperature was considered.
