The novel vapor method gave 40 C-% yield of glucose in hydrolysis of crystalline cellulose. Investigation of effects of crystallinity of polysaccharides on the hydrolysis revealed that the vapor method is significantly effective for the hydrolysis of crystalline polysaccharides. The catalytic effect of various molecules was examined as vapor catalyst. Formic acid accelerated the yield of glucose, whereas acetic acid and methanol inhibited the reaction, and it was suggested that the molecular size and polarity have affected the catalyst activity.

新的气相法在水解结晶纤维素中得到40 C-%的葡萄糖产率。研究了多糖结晶度对水解的影响，结果表明，水蒸气法对结晶多糖的水解效果显著。考察了不同分子作为气相催化剂的催化效果。甲酸促进了葡萄糖的生成，而乙酸和甲醇抑制了反应，这表明分子大小和极性影响了催化剂的活性。
