Document Type and Number:

WIPO Patent Application WO/2012/039462

Kind Code:

A1

Abstract:

The present invention relates to a method for producing a cellulose solution, including: performing ozonation that brings cellulose-containing material into contact with ozone; and performing alkaline treatment that brings the result of the ozonation into contact with an alkali aqueous solution to dissolve at least cellulose out of the cellulose-containing material brought into contact with the ozone into the alkali aqueous solution. According to the present invention, it is possible to provide a method for producing a cellulose solution capable of dissolving cellulose in an easier manner, a method for producing a cellulose precipitate capable of recovering cellulose from the cellulose solution, and a method for saccharifying cellulose using the cellulose precipitate.
