| 英文摘要 | A new dual catalyst system composed of choline-derived ionic liquids (ils) and pd/c was developed for the selective hydrogenolysis of kraft lignin to mono-phenols. among a series of investigated choline-derived ils, [ch][meso3] displayed a strong acidity, good thermal stability, and excellent lignin solubility. under the reaction conditions of the mass ratio of [ch][meso3] to pd/c being 1, the pd/c loading of 3.5 wt %, h-2 pressure of 2.0 mpa, reaction time of 5 h, and temperature of 200 degrees c, the conversion of kraft lignin and the selectivity to phenol (pl) and catechol (col) reached 20.3%, 18.4%, and 18.1%, respectively. in order to rationalize the formation of pl and col in our [ch][meso3]-pd/c system, the hydrogenolysis of a suitable lignin model compound (guaiacylglycerol-beta-guaiacyl ether) was studied under the same condition for kraft lignin. the results suggested that the mechanism involved fragmentation of lignin catalyzed by both acid and pd/c, followed by acid-catalyzed c-o and c-c cleavage of the fragmented compounds resulting in the formation of pl and col. |
