摘要
发现一种含催化剂的甲酸溶液体系能有效溶解竹浆纤维,竹浆纤维在溶解过程中纤维素发生了水解,水解后甲酸能清洁回收循环使用,并得到固体的可溶性糖产物。将竹浆纤维放入含催化剂的甲酸溶液0.5h后,开始溶胀,1.0h后逐渐溶解,颜色开始变深,呈浅墨绿色,2.0h后基本溶解,溶液颜色也逐渐变深,4.0h后呈完全溶解状态。60℃反应6.0h后,经过处理可从反应体系中得到葡萄糖、纤维二糖、纤维三糖、纤维四糖、纤维五糖和纤维六糖固体产物,葡萄糖的得率达54.5%。
It was found that bamboo fiber could be effectively dissolved in formic acid solution containing a catalyst. Cellulose of bamboo fiber was hydrolyzed during dissolution. Formic acid could be cleanly recycled for using. The solid product of soluble sugars was obtained. Bamboo fiber started to be swelled after 0.5 h of addition to formic acid solution, It was gradually dissolved after 1.0 h and the color of solution changed to light green black. It was basically dissolved after 2.0 h and the color of solution gradually became darker. It was completely dissolved after 4.0 h. After 6.0 h of reaction at 60 ℃ treatment, the solid product containing glucose, cellobiose, cellotriose, cellotetrose, cellopentose and cellohexaose was obtained from the reaction system. The yield of glucose was 54.5 %.
