| 摘 要： | 以杂多酸H3PW12O40为催化剂,1-烯丙基-3-甲基咪唑氯盐(Amim]Cl)离子液体为溶剂,在较温和条件下对微晶纤维素(MCC)进行降解实验。研究了反应温度、反应时间、加水量及催化剂用量等条件对降解反应的影响。研究结果表明,以离子液体Amim]Cl(2.0 g)为溶剂,降解微晶纤维素(0.1 g,0.6 mmol),当催化剂用量为0.09 当量(eq)、加水量为0.07 mL、微波加热160℃反应30 min 时,微晶纤维素的降解效果最佳,其中可还原糖(TRS)的收率可达66.8%,葡萄糖收率为32.8%,纤维二糖收率为17.6%。 |

| Abstract: | Microcrystalline cellulose is degraded in 1-allyl-3-methylimidazolium chloride (Amim]Cl) ionic liquid using heteropoly acid H3PW12O40 as catalyst under the mild environment. The effects of reaction temperature and time, the amount of catalysts and water on the degradation of cellulose have been investigated in details. When using 0.09eq of H3PW12O40, 0.07 mL of water, ca. 0.6 mmol of microcrystalline cellulose and 2.0 g of Amim]Cl under microwave irradiation for 30 min at 160℃, 66.8% of total reducing sugar (TRS) yield, 32.8% of glucose yield and 17.6% of the cellobiose yield can be obtained. |
| Keywords: | microcrystalline cellulose heteropoly acid total reducing sugar glucose |
