Abstract:

Fe-doped SO42-/SnO2 (STF) solid acid catalysts with different amounts of iron were prepared via co-condensation, followed by sulfation and calcination. These materials were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray powder diffraction (XRD), N2 adsorption-desorption analysis (BET), thermogravimetric (TG) analysis, and scanning electron microscopy (SEM). The Fe-doped catalysts exhibited more activity than undoped catalysts in acetalization reactions of 4-tert-butylcyclohexanone and diols. The catalytic acetalization of several ketones and 1,2-diols with the SO42-/SnO2-Fe2O3 catalysts (with the Fe/Sn molar ratio of 0.5) were studied. The influence of the reaction time and the amount of the catalysts on the acetalization were also investigated. In addition, the high performance of this Fe-modified catalyst was demonstrated in the Baeyer-Villiger oxidation of cyclic ketones. The catalyst can be recycled several times without any significant loss in catalytic activity.
