一种在离子液体中高效水解纤维素的方法

, 2008
本发明涉及纤维素的水解，具体地说是一种在离子液体中高效水解纤维素的方法；以可溶解纤维素的离子液体为溶剂，以≥1摩尔当量的水为反应物，以催化量至化学计量的无机酸为催化剂，纤维素在常压下于70 ℃～100℃反应2分钟～9小时；反应结束后，用冷水淬灭反应、用碱中和，即得纤维素水解液；对水解液中总还原糖和葡萄糖进行化学定量分析，结果表明还原糖产率最高可达73％，对应的葡萄糖产率达到53％。与传统水解方法相比，本发明无需预处理过程、反应条件温和、水解活性高、反应速度快、酸耗少、对反应器的抗腐蚀性要求不高 ...

一种再生纤维素复合膜及其制备方法

, 2012
本发明公开了一种再生纤维素复合膜，由以下质量百分比60％～97.5％的纤维素和2.5％～40％的卤代高分子组成，具有高韧性、可生物降解、相容性好等特点。本发明还公开了一种再生纤维素复合膜的制备方法，包括：1)将纤维素加入到预处理有机溶剂中，在155～165℃处理0.5～1h，再经过压榨；2)将压榨得到的预处理后的纤维素加入到共溶有机溶剂体系中，搅拌直至产生凝胶，再静置12～30h，得到透明溶液；3)向透明溶液中加入卤代高分子，搅拌共混20～40min，得到混合溶液；4)将混合溶液经过成膜和成膜后处理 ...
