摘要

PROBLEM TO BE SOLVED: To provide a method capable of dissolving cellulose by using a substance having comparatively high safety under mild conditions.;SOLUTION: The method for producing aqueous cellulose solution includes a step of bringing a cellulose purified substance or substance containing cellulose into contact with aqueous hydroxide quaternary ammonium solution, wherein the total concentration of halogen compounds of alkali metals and/or halogen compounds of alkali earth metals, dissolved in the aqueous hydroxide quaternary ammonium solution is 1 wt.% or less in a state contacted with the cellulose raw material. Alternatively, the method for producing aqueous cellulose solution includes a step of bringing a cellulose raw material into contact with an aqueous hydroxide quaternary ammonium solution, wherein the cellulose raw material is brought into contact with the aqueous hydroxide quaternary ammonium solution is performed in the presence of a cyclic polyether.;COPYRIGHT: (C)2013,JPO&INPIT
