Abstract: 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%.

Key words: cellulose, hydrolysis, dissolution, sugar
