<p><P>PROBLEM TO BE SOLVED: To provide a method for producing a cellulose solution, which is excellent in the solubility of a pulp, and can reduce the time and energy needed for drying. <P>SOLUTION: The method for producing a cellulose solution includes dissolving a pulp in an ionic liquid. The water content of the pulp is made to be≥50 mass%. The dissolution of the pulp in the ionic liquid is carried out at a heated temperature of≥70°C. The dissolution of the pulp in the ionic liquid is preferably carried out under a pressure lower than the vapor pressure of water in a mixture of the pulp and the ionic liquid at a temperature at the dissolution. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
