Solvent-free acetalization of glycerol over mesoporous solid acid catalyst |
| 초록 |
Biodiesel has gained a considerable attention in recent years due to global warming and decrease of the fossil fuel. The production of biodiesel involves the transesterification of vegetable oils with methanol to afford biodiesel and glycerol, produced as byproduct. Acetalization of glycerol has been reported to yield five and six membered acetal. In this research, glycerol conversion with acetone has been studied using mesoporous WO3/rod-type SBA-15 (WO3/R-SBA-15) as a catalyst. A series of catalysts with varying WO3 loadings (5~20 wt%) were prepared by incipient wetness impregnation method. In the catalytic experiment, variant molar ratios of glycerol to acetone were fed, and WO3/R-SBA-15 catalyst was added. Among the catalysts, 15 wt% WO3/R-SBA-15 was found to be the most active catalyst in acetalization reaction at 30 ℃. The catalyst exhibited 99% conversion with 97% selectivity for the five-membered cyclic product. The excellent performance of the catalyst is mainly due to their high specific surface area and strong surface acid properties. |
