中文摘要：
本文对甲酸-盐酸混合溶液水解麦草制备木糖的工艺进行研究。实验发现含10%HCl的饱和甲酸溶液在65℃水解麦草0.5h后,麦草木糖的水解得率达到23.62%。水解液经D311阴离子交换树脂脱酸脱色、活性炭脱色、真空结晶等一系列工艺后,结晶木糖产率为干燥麦草质量的15.87%,工艺可行。
英文摘要：
The production of xylose via hydrolysis of straw in a mixture of formic acid and hydrochloric acid was investigated. Results showed that the yield of straw xylose reached 23.62 % with saturated formic acid containing 10 %HCl, reaction time of 0.5 h and temperature of 65 ℃. The hydrolysate was purified with D311 and activated carbon for decoloration and then crystallized, giving the pure xylose with the yield of 15.87 %. Results indicated that this technology was available.
