| 摘 要： | 合成了8种基于Mo8O26的钼多金属氧酸盐,采用红外(FT-IR)和核磁共振(NMR)对其结构进行表征,并将其应用于催化纤维素水解。以离子液体1-烯丙基-3-甲基咪唑氯盐(Amim]Cl)为溶剂进行微晶纤维素(MCC)水解反应,考察催化剂及其用量、反应温度、反应时间等条件对水解反应的影响。研究结果表明,本文所制备的钼多金属氧酸盐对微晶纤维素水解反应均具有较好的催化活性。在微波辅助加热条件下,当催化剂(CH3)4N]4Mo8O26用量为10 wt%,在170 ℃反应20 min时,纤维素可完全转化,微晶纤维素TRS和葡萄糖收率最高分别为84.5% 和41.5 %。

| Abstract: | 8 kinds of Mo8O26 based compounds were synthesized and the structure of these compounds were characterized by NMR and FT-IR. Microcrystalline cellulose was hydrolyzed to produce the total reducing sugar (TRS) in ionic liquid Amim]Cl using molybdenum polyoxometalate as catalyst under microwave irradiation conditions.The effects of catalyst and its dosage, reaction temperature and reaction time on the hydrolysis reaction were investigated. The results indicated that the molybdenum polyoxometalates prepared in this paper have good catalytic activity for the hydrolysis reaction of microcrystalline cellulose. The cellulose can be completely converted with the addition of 10wt% of catalyst (CH3)4N]4Mo8O26 under the microwave-assisted heating condition in the ionic liquid Amim]Cl at 170 ° C for 20 min. The highest TRS and glucose yields of MCC were 84.5 % and 41.5% respectively. |
