AbstractIn our previous work, we have developed a new catalyst Ni-W2C/AC over which the complete conversion of cellulose was realized and EG was selectively formed as a yield as high as 61%.[1] To study this new reaction mechanism, we investigated the chemical transformation of glucose in the present work. The results show that the glucose (1 wt% in water) can be selectively converted into EG with Ni-W2C/AC catalyst. Under the optimized conditions, i.e., 2MPa H2 and 235 oC, 1% aqueous glucose was converted into EG, 1,2-PG, sorbitol, and mannitol with a yield of 38.2%, 5.3%, 11%, and 7.8%, respectively. It is noted that the EG yield here from the glucose is significantly lower than that from the cellulose we reported previously. This result implies that in the reaction for cellulose conversion to EG, the glucose was formed probably as an intermediate in the first step, and then it undergoes hydrogenation and hydrogenolysis, producing hexitols (sorbitol and mannitol) and low-molecular polyols such as EG and 1,2-PG. The competition of various reactions would lead to lowering of the EG yield. On the other hand, if the concentration of glucose in the reaction medium is low enough, just as the case of cellulose transformation, many undesired reactions would be restrained to a large extent, as a result, the selectivity for EG formation was enhanced.
