제목 Highly-efficient conversion of glycerol to solketal over mesoporous WOx/SnO2 solid acid catalysts
초록 The acetalization of glycerol with acetone to yield 2,2-dimethyl-1,3-dioxolane-4-methanol (solketal) was successfully catalyzed by mesoporous WOx/SnO2 catalysts under solvent-free conditions. In this work, a series of mesoporous WOx/SnO2 catalysts with various tungsten oxide loadings (5~20) wt.% were prepared by wet-impregnation method. The synthesized catalysts were systematically analyzed using various techniques. Characterization results revealed that the WOx (≤ 20 wt.%) was highly dispersed on the surface of mesoporous SnO2, and the strong interaction between WOx and SnO2. Catalytic acetalization over 20wt% WOx/SnO2 catalyst resulted in the highest glycerol conversion (100%) and solketal selectivity, due to the addition of tungsten oxide enhances the surface acidic properties of mesoporous SnO2. Additionally, there was no decrease in activity  of the used catalyst after servel times recycle-test which indicated the reusability of catalyst.
