Solvent used for dissolving polysaccharide and method for manufacturing molded article and polysaccharide derivative using this solvent

摘要

There is provided a solvent that can uniformly dissolve a polysaccharide within a short time period regardless of the crystal form of the polysaccharide and without requiring any special pretreatment. The solvent includes a tetraalkylammonium acetate represented by the below-indicated formula; and an aprotic polar solvent. A content of the aprotic polar solvent is 35 wt % or more.;
In the formula, R1, R2, R3, and R4 each independently represent an alkyl group having 3 to 6 carbon atoms.
