摘　　要：为了从蒸汽爆破预处理后得到的甘蔗叶中提取木糖,采用酸催化水解法处理甘蔗叶研究了提取木糖过程中各因素对木糖溶出量的影响。结果表明,木糖得率随硫酸浓度先增大后减小,随液料比增大而增大,随反应时间延长先增大后减小,随水解温度增高,先增大后减小。最佳酸解工艺条件是,硫酸浓度2%,反应时间2 h,反应温度100℃,液料比是11:1(v/w)。In order to obtain extract xylose from steam explosion pretreatment of sugar cane leaves to study the process of extracting xylose infl uence of various factors on the dissolution of the processing of sugar cane leaves by acid catalyzed hydrolysis. The results showed that the yield of xylose concentration of sulfuric acid after the fi rst increases with the decrease, with the liquid ratio increases, decreases with increasing reaction time after the fi rst, with the hydrolysis temperature increased, then decreased. Best process conditions of acid hydrolysis, the concentration of sulfuric acid 2%, reaction time 2 h, reaction temperature 100 ℃, liquid ratio is 11：1（v/w）.
