| 摘 要： | 对稻草高温热水预提取半纤维素的条件进行了研究。结果表明,预提取温度和时间影响水解液中还原糖的含量。从得率和还原糖含量两个方面考虑,最佳的预提取条件为150℃,升温1 h,保温1.5 h,此时水解液中还原糖含量为4.65 g/L。半纤维素预提取后,纸张的抗张指数明显下降,撕裂指数增加。

| Abstract: | Conditions of hemicellulose pre-extraction of rice straw were discussed using hot water. The results shows temperature and extraction time influence the concentration of reducing sugar in hydrolyzate. Considering two points of the concentration of reducing sugar and the yield of rice straw,the optimum condition of pre-extraction was 1h of heating time and 1. 5 h holding time at 150 ℃. The concentration of reducing sugar in hydrolyzate was 4. 65 g / L. After hemicellulose pre-extraction,the tensile index of paper decreased obviously,and the tear index of paper increased. |
