| 摘 要： | 以榉木木聚糖为原料,采用炭基固体酸催化剂(AC-SO_3H)催化水解制备得到低聚木糖。分别考察反应时间、反应温度、催化剂用量对低聚木糖收率及各组分收率的影响,并通过正交试验设计确定最佳工艺条件为20 m L蒸馏水,0.5 g木聚糖、0.2 g AC-SO_3H、反应时间3 h、反应温度140℃。并在此条件下,分别以AC-SO_3H、M-ACSO_3H、S-AC-SO_3H为催化剂,考察不同催化剂对低聚木糖收率的影响,结果表明以AC-SO3H为催化剂时低聚木糖收率最大为66.60%。

| Abstract: | In the current study, xylooligosaccharides (XOS) were prepared by catalytic hydrolysis of beech wood xylan using carbon-based solid acid catalyst (AC-SO3H). The effects of reaction time, temperature and catalyst dosage on the yield of XOS were investigated. Using orthogonal array design, the optimal hydrolysis conditions were determined as 0.5 g of xylan, 0.2 g of AC-SO3H, and reaction time 3 h at 140 ℃. Under these conditions, the effect of different catalysts, namely, AC-SO3H, M-AC-SO3H and S-AC-SO3H, on XOS yield was investigated. The results showed that the highest yield of XOS of 66.60% was obtained by using AC-SO3H. |
