(1) Reaction constants in the hydrolysis of pure cellulose and rice hulls with dilute H_2SO_4 were compared.(2) Decomposition constants of glucose and xylose in dilute H_2SO_4 at 125〜180℃ were examined, and it was found that glucose shows the stability as high as 3 times that of xylose.(3) Hydrolysis of cellulose with concentrate H_2SO_4 was investigated to obtain the best condition for saccharification.The result is as follows : When cellulose is dissolved in 76 % H_2SO_4,followed by dilution to about 8% H_2SO_4 and heating at 100℃ for about 1 hr, the yield of glucose is highest, namely 93-94% of cellulose.
