Rate equations for main-hydrolysis of cellulosic materials in vibrating mill are presented.A method of sulfuric acid distribution into cellulosic materisl was realized by such successive operations as steeping--drewatering--freeze-drying.The effects of the reaction temperature and presence of the acid on the rate of the hydrolysis were observed.The rate constants were found to be expressed by the following equations : K=0.1545γ^<0.788>C^<3.22>exp{-9450/RT}where acid mixing ratio, γ(sulfuric acid g as 100% in concn./dry matter g), ranges from 0.043 to 0.220,acid concentration, C, ranges from 51% to 81%, and temperature from 50℃ to 80℃, K=2360 exp{-11520/RT}where temperature ranges from 150℃ to 220℃, min^<-1> means the first-order reaction constant, T°K, absolute temperature, R cal/mole °K gas constant.
