| 英文摘要 | Microcrystalline cellulose (mcc) is hydrolyzed to an appreciable extent (70 %) by using 1-(4-sulfonic acid) butyl 3-methylimid azolium hydrogen sulfate (il-1) as effective catalyst valuable chemicals such as 5 hydroxymethyl furfural (hmf) and furfural, are obtained in relatively high yields (15% and 7%, respectively) interestingly the introduction of fecl2 as catalyst into il-1 further enhances the catalytic activity as proved by the higher, conversion of mcc (84%) and higher yields of hmf and furfural (34% and 19%, respectively) under the same experimental; conditions although small amounts of levulinic acid (la) and total reducing sugars (trs) were also found the hydrolysis of mcc scarcely proceeded, or showed a lower efficiency in the absence of catalyst (4%) or with al2o3 (7%), inorganic acids (<= 65%) or several other ionic liquids (<= 24%) as catalyst dimers of furan compounds were detected as the main by-products as analyzed by hplc ms from the mass spectrometry analysis, the components of the gas-phase products were determined to be methane ethane, co co2, and h-2 a mechanism to explain the high activity of fecl2 in the il-1 system is proposed recycling of the il 1 catalyst showed an almost constant activity during five successive trials the simple and effective catalyst system may prove valuable in facilitating the energy-efficient and cost-effective conversion of biomass into biofuels and platform chemicals |
