Abstract

See full text

Provided is a method for solubilizing cellulose in which cellulose can be solubilized in a short period of time with a low amount of excess decomposition and without the use of a catalyst or other chemicals. A starting material containing cellulose is pulverized to reduce the crystallization thereof, adjusted for moisture content, reacted with water in the absence of a catalyst, and converted into a water-soluble component. At this point, the reaction is performed at a temperature of 100° C. or more and less than 300° C., and a total pressure of 0.05 MPa or more and less than 10 MPa. Water is added and extracted from the water soluble component, and solid-liquid separation is performed to separate the solids and the aqueous solution.
